. The diversity gain (coherent Gain) is the slope of the curve of BER
N0
and is a function of average SNR- as the diversity gain increases, the slope becomes
sharper. By smart ST processing with CSI exploitation, the BER is bounded by (2.52)
and in Rician channel, the bound becomes (2.48).
The bounds in (2.48) and in (2.52) are plotted in Fig. 5 for different values of N.
