The availability of a noiseless feedback channel can allow for simplistic transmission schemes with very high reliability; such advantages were solidified by a linear feedback scheme developed by Schalkwijk and Kailath (S-K). However, the S-K scheme and related techniques rely on the presence of a noiseless feedback channel which is not practical. In this paper, we look at introducing the notion of...
This paper concerns a simple limited feedback scheme taking temporal correlation into account during the feedback design in slow fading environment. In this method, the transmitter and the receiver reuse the past channel state information (CSI) as side information. Feedback, that is designed to leverage the side information, is sent from the receiver to the transmitter using a predetermined update...
