We propose distributed compression for the uplink channel of a backhaul-constrained coordinated cellular network. In the network, N multiple-antenna base stations compress their received signals using a distributed Wyner-Ziv code, and then send the compressed vectors to a central BS, which centralizes decoding. For a single-user network, the compression codes at the BSs are optimized in this paper, considering the userpsilas achievable rate as the performance metric.
