How many bits should be reported in quantized cooperative spectrum sensing?

peer reviewedWe introduce an algorithm for optimizing sensing parameters including the number of sensing samples and the number of reporting bits of a quantization-based cooperative spectrum sensing scheme in cognitive radio networks. This is obtained by maximizing the network throughput subject to a target detection probability. With Rayleigh fading and energy detector, the proposed algorithm simultaneously optimizes the number of sensing samples at a local node, the number of bits for quantizing local sensing data and the global threshold at a fusion center.R-AGR-0203-1 > C14/IS/8225172: SATSENT > > CHATZINOTAS Symeo
