Abstract

A communication device may comprise a plurality of distributed transceivers and one or more corresponding antenna arrays. A processor may configure a first distributed transceiver to receive signals comprising one or more first data streams via one or more first communication links. The processor may configure a second distributed transceiver to receive signals comprising one or more second data streams via one or more second communication links. The processor may determine a channel response matrix associated with communication of the one or more first data streams via the one or more first communication links and/or the one or more second data streams via the one or more second communication links. The processor may optimize one or both of link capacity and/or link reliability of the one or more first communication links and/or the one or more second communication links based on the determined channel response matrix.

First claim

What is claimed is:

1. A method, comprising:
in a communication system comprising a plurality of distributed transceivers and one or more corresponding antenna arrays:
configuring a first distributed transceiver of said plurality of distributed transceivers to transmit one or more first data streams via one or more first communication links over a first distance;
configuring a second distributed transceiver of said plurality of distributed transceivers to transmit one or more second data streams via one or more second communication links over a second distance;
determining a channel response matrix for communication of said one or more first data streams via said one or more first communication links and/or said one or more second data streams via said one or more second communication links based on a plurality of phase elements of said first distributed transceiver and said second distributed transceiver;
adjusting an effective phase value of said plurality of phase elements of said determined channel response matrix such that said effective phase value of said plurality of phase elements becomes substantially an odd multiple of 180°, based on change in said second distance of said one or more second data streams transmitted by said second distributed transceiver with maintenance of said first distance of said one or more first data streams transmitted by said first distributed transceiver; and
maximizing one or both of link capacity and/or link reliability of said one or more first communication links and/or said one or more second communication links based on said adjustment of said effective phase value of said plurality of phase elements of said determined channel response matrix.

2. The method according to claim 1 , comprising determining a range of phase conditions over which said maximization is acceptable.

3. The method according to claim 2 , comprising adjusting a phase sum corresponding to said first distributed transceiver and/or said second distributed transceiver based on a phase difference between said first distributed transceiver and said second distributed transceiver, wherein said phase sum is adjusted to maximize one or both of said link capacity and/or said link reliability.

4. The method according to claim 2 , comprising adjusting said determined range of phase conditions based on signal to noise ratio on said one or more first communication links and/or on said one or more second communication links.

5. The method according to claim 2 , comprising determining said range of phase conditions over which said maximization is acceptable based on one or more of training signals and/or pilot signals communicated via said one or more first communication links and/or via said one or more second communication links.

6. The method according to claim 2 , comprising adaptively displacing said first distributed transceiver, an antenna communicatively coupled to said first distributed transceiver, said second distributed transceiver and/or an antenna communicatively coupled to said second distributed transceiver to satisfy said determined range of said phase conditions over which said maximization is acceptable.

7. The method according to claim 6 , wherein said displacement of said first distributed transceiver, said antenna communicatively coupled to said first distributed transceiver, said second distributed transceiver and/or said antenna communicatively coupled to said second distributed transceiver occurs spatially in x-coordinate, y-coordinate and/or z-coordinate.

8. The method according to claim 2 , comprising adaptively controlling adjustment of a phase center of an antenna communicatively coupled to said first distributed transceiver and/or adjustment of a phase center of an antenna communicatively coupled to said second distributed transceiver to satisfy said determined range of said phase conditions over which said maximization is acceptable, wherein said phase center is adjusted by activating one or more antennas in first distributed transceiver and/or by activating one or more antennas in second distributed transceiver based on said channel response matrix.

9. The method according to claim 1 , wherein said one or more first data streams and said one or more second data streams comprise different polarizations.

10. The method according to claim 1 , wherein said one or more first data streams and said one or more second data streams comprise similar polarizations.

11. A system, comprising:
one or more processors for use with a communication device comprising a plurality of distributed transceivers and one or more corresponding antenna arrays, said one or more processors being operable to:
configure a first distributed transceiver of said plurality of distributed transceivers to transmit one or more first data streams via one or more first communication links over a first distance;
configure a second distributed transceiver of said plurality of distributed transceivers to transmit one or more second data streams via one or more second communication links over a second distance;
determine a channel response matrix for communication of said one or more first data streams via said one or more first communication links and/or said one or more second data streams via said one or more second communication links based on a plurality of phase elements of said first distributed transceiver and said second distributed transceiver;
adjust an effective phase value of said plurality of phase elements of said determined channel response matrix such that said effective phase value of said plurality of phase elements becomes substantially an odd multiple of 180°, based on change in said second distance of said one or more second data streams transmitted by said second distributed transceiver with maintenance of said first distance of said one or more first data streams transmitted by said first distributed transceiver; and
maximize one or both of link capacity and/or link reliability of said one or more first communication links and/or said one or more second communication links based on said adjustment of said effective phase value of said plurality of phase elements of said determined channel response matrix.

12. The system according to claim 11 , wherein said one or more processors are operable to determine a range of phase conditions over which said maximization is acceptable.

13. The system according to claim 12 , wherein said one or more processors are operable to adjust a phase sum corresponding to said first distributed transceiver and/or said second distributed transceiver based on a phase difference between said first distributed transceiver and said second distributed transceiver,

15. The method according to claim 1 , further comprising switching at least one of said first distributed transceiver or said second distributed transceiver between a first mode of operation and a second mode of operation based on a signal to noise ratio (SNR) associated with said at least one of said first distributed transceiver or said second distributed transceiver.
