Abstract
Official abstract text for this publication.
A wireless spectrum is shared between a primary communication system and secondary communication system operating in an overlapping geographical region. A primary transmitter broadcasts a primary signal, and a secondary transmitter transmits a secondary signal, both using a primary wireless spectrum assigned to the primary communication system. The secondary transmitter transmits the secondary signal to a secondary receiver with power (1−α)P and transmits the primary signal with power αP. The parameter α is computed to ensure a predetermined quality of reception of the primary signal by a hypothetical primary receiver located near the secondary transmitter. The secondary transmitter may compute a feasibility of using cognitive transmission and, when the computed feasibility exceeds or does not exceed a feasibility threshold, it selects to enable or disable, respectively, the use of the primary wireless spectrum to transmit from the secondary transmitter.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for wireless spectrum sharing, the method comprising: broadcasting a primary signal from a primary transmitter using a primary wireless spectrum assigned to a primary communication system; transmitting a secondary signal from a secondary transmitter to a secondary receiver using the primary wireless spectrum assigned to the primary communication system, wherein the secondary transmitter and the secondary receiver belong to a secondary commun…
