  abstract: Wyner-Ziv coding problem exploits the correlation between two signals (one is the source and the other is the side information) and thus makes it possible to encode the source signal alone and to decode it jointly with the help of the side information at the decoder. Nested lattice quantization provides a practical scheme for Wyner-Ziv coding. We examine the high-rate performance of nested lattice quantizers and give the theoretical performance for general continuous sources. Based on our analysis, a new practical Wyner-Ziv coding scheme called Slepian-Wolf coded nested lattice quantization (SWC-NQ) is proposed. Theoretical analysis shows that for the quadratic Gaussian case and at high rate, SWC-NQ performs the same as conventional entropy-coded lattice quantization with the side information available at both the encoder and the decoder. Practical designs of one- and two-dimensional nested lattice uantizers, together with multi-level LDPC codes for Slepian-Wolf coding, give performance close to the theoretical limits of SWC-NQ for the quadratic Gaussian case. Furthermore, we apply our code design in cooperative networks as practical implementations of the cooperative strategies. In cooperative networks, relaying is an essential component to gain the cooperative diversity. Following the latest development in practical distributed source-channel coding, we studied Compress-forward (CF) coding with BPSK modulation for the relay channel, where Wyner-Ziv coding is applied at the relay to exploit the joint statistics between signals at the relay and the destination. Practical issues such as quantizer design and selection of channel code parameters are discussed in detail. Simulation results show that, by using LDPC codes for error protection at the source and nested scalar quantization and IRA codes for Wyner-Ziv coding (or more precisely distributed joint source-channel coding) at the relay, our practical implementation comes within only 1.6-3 dB from the theoretical li…
