Distributed reception of fading signals in noise

摘要

A multiple antenna diversity scheme is investigated for digitalwireless communications. In this scheme the antenna observations areimmediately quantized and only the quantized values are sent to a fusioncenter to decide which symbol was transmitted. The case where finequantization is impractical is considered, so that distributed detectionprinciples apply. The optimum reception scheme is described for the casewhere frequency shift keying is employed. Multiple bit quantizationschemes are considered for cases where the observations at each antennaare influenced by slow Rayleigh fading and Gaussian additive noise. Somenumerical results are provided
