N2 - In this work, we exploit the capacity approaching capability of low density parity check (LDPC) codes over wireless relay channels. We consider the classical full-duplex relay channel model under both ergodic and non-ergodic scenarios, and propose two practical relaying schemes. By comparing with the theoretical information rate bounds, we show that the LDPC coded relay systems can approach the ergodic/outage information rates (i.e., constrained channel capacities) very closely. Specifically, we show that they can even outperform the existing turbo coded relay systems under appropriate code design. In addition, based on the measure of average mutual information, we analyze the convergence behavior of the proposed schemes which also demonstrates their great potential to perform near capacity over both ergodic and non-ergodic wireless relay channels.
