Distributed LDPC coders in cooperative relay networks

In this paper, a new distributed LDPC coder is developed in the cooperative relay networks. Although the proposed scheme requires to use the same bandwidth as the conventional approach over OFDM based transmission, the use of the hybrid ARQ can be reduced. In addition, the overall performance can be improved using the proposed approach.
