Capacity-achieving feedback scheme for flat fading channels with channel state information
Jialing Liu, Nicola Elia, Sekhar Tatikonda · 2004
In this paper, we propose a capacity-achieving feedback scheme for an AWGN i.i.d. flat fading channel with channel state information. This scheme considerably reduces the encoding and decoding complexity and delay, and it extends the Schalkwijk and Kailath scheme to i.i.d. time-varying channels.
