Abstract

We present an overview/review of various approaches to channel estimation and equalization for wireless mobile systems with a brief discussion of channel precoding techniques. Since approaches to channel estimation depend upon the underlying channel model, we also review various approaches to channel modeling. First we present the relevant channel models including time-invariant and time-variant (doubly-selective) models where emphasis is on basis expansion modeling. Channel modeling is followed by a discussion of various approaches to channel estimation including ...
