Wireless multicasting (also called common information broadcasting) is a technique where a common information message is transmitted to multiple users. This is typically accomplished by having the basestation broadcast out a signal representing this message. In this paper, we consider a multicasting scheme where the basestation transmits the multicasting signal without any a-priori knowledge of the...
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...
The integration of the feedback channel into a coding scheme cannot increase capacity but still has many benefits such as higher reliability and lower complexity. In the class of linear feedback coding schemes, one of the most well-known is the Schalkwijk-Kailath coding scheme. Using the same framework, an optimized coding scheme is produced using linear algebraic tools, and this scheme is compared...
