Practical cooperative diversity protocols often rely on low-cost radios that treat multiple in-band signals as noise and thus require strictly orthogonal transmissions. We analyze ...
Abstract— According to the cognitive radio paradigm, a terminal or subsystem will opportunistically select a frequency band for data transmission. Because the spectrum is shared,...
During the last decade, many works were devoted to improving the performance of relaying techniques in ad hoc networks. One promising approach consists in allowing the relay nodes ...
