Recently wireless relay channels have been receiving significant
attention due to the increased spatial diversity and channel
capacity. In this presentation, we consider several channel coding
aspects of such channels with the objective of obtaining codes that
approach the capacity bounds. We consider the classical relay
channel model for both ergodic and non-ergodic fading scenarios, and
develop turbo coding and LDPC coding based schemes. Using the
designed distributed coding schemes, we demonstrate that it is
possible to operate ``near'' the channel capacity. Furthermore, we
point out some methods of simplified receiver design, and extend
some of the coding schemes and the decoding algorithms to the case
of frequency selective fading channels. The latter extension could
find applications in underwater acoustic communications.
