... gains The SNR gain comes from the (coherent) addition of the incoming streams at the receiver antennas. It is obtained by averaging the instantaneous SNR over the channel realizations and indicates ... that degrades the performance of the system due to the in- phase misalignment of the incoming streams. This paper presents the losses of the signal-to-noise r...
