WebIn the case of a fading SISO channel, the received signal at the k-th symbol instant is y[k] = h[k]x[k]+n[k]. To ensure a compatible measure of power, set E n h[k] 2 o = 1 and E n x[k] 2 o ≤ Es. At this point there are two possibilities, a ﬁxed fading channel with a random but unchanging channel gain and a slow, but ﬂuctuating channel. WebFor 2 × 2 systems, the above results show that i.i.d.
