... of channel estimation error. 2.2. Channel estimation error In practical wireless communication systems, the channel co- efficients {g k (l)} are unknown to the receiver, and the corre- sponding channel ... the existence of noise and interference. We assume that training symbol-based channel estimation [16] is applied to provide the channel estimates. On denoting the cha...
