Abstract

We consider a Cloud Radio Access Network (C-RAN) uplink system composed of single user, multiple remote radio heads (RRH) and baseband unit (BBU) pool. The user encodes the messages with rateless code which are then modulated and sent. Each RRH which covers the user quantizes the received signals and transfers them to the BBU pool through the high rate fronthaul link. The BBU pool applies belief propagation (BP) algorithm for joint decompression and decoding for the user information. In order to further improve the performance of the system, we resort to the extrinsic mutual information transfer (EXIT) analysis to optimize the degree profile of the rateless code. The numerical simulation shows that the BER performance of the proposed rateless coded scheme is close to the theoretical upper bound.
