Abstract
Official abstract text for this publication.
The present invention relates to space-time or space-frequency coding in cellular systems. The same data is transmitted from different antennas with different coverage areas, corresponding to different cells. The different data streams have different parts of the space-time block codes applied. A mobile terminal can combine the different parts of the space-time block codes in different received signals. This provides better performance than the known techniques for single frequency networks. The invention can also be applied to antennas with different coverage areas from the same site, and different beams formed with antenna arrays.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for receiving an information data stream in a receiver device, the method comprising: receiving at least two different pilot signals; detecting at least one synchronization signal; determining a timing reference from the synchronization signal; determining at least two channel estimates wherein each of the at least two channel estimates is based on at least one of: one or more of the at least two received pilot signals; or one or more…
