Fig. 2From: Performance analysis of spatial multiplexing MIMO-MFSK based on energy detection for fast-fading environmentsSignal-dependent noise distribution at low SNR. The figure shows the distribution of the received signal when the transmitted signal is \({\mathbf{s}}_{{1}}\),\({\mathbf{s}}_{{2}}\) and \({\mathbf{s}}_{{3}}\) at low SNRBack to article page
