We consider a joint Slepian-Wolf/Dirty-paper coding (SW-DPC) setup where a binary source needs to be transmitted over an additive white-Gaussian channel in the presence of interference known only at the encoder, as well as correlated side-information available only at the decoder. We propose a practical joint SW-DPC framework that uses a single low-density parity-check code coupled with trellis coded quantization to simultaneously provide error protection (in the face of noise and interference) and compression (in the face of correlated side-information available at the decoder). Simulation results indicate that the proposed joint SW-DPC scheme with finite-length codes outperforms a scheme with separate SW and DPC by 0.3 dB. In addition, we show that our joint SW-DPC code designed for one set of channel conditions is capable of achieving negligible bit-error rates for many other channel conditions as well. More specifically, it achieves successful decoding for a wide variety of channel conditions for which a separation-based scheme fails.

ConferenceIEEE International Conference on Communications 2013
Abbreviated titleICC 2013
OtherThe International Conference on Communications (ICC) is one of the two flagship conferences of the IEEE Communications Society, together with IEEE Globecom. Each year the ICC conference attracts about 2-3.000 submitted scientific papers, a technical program committee involving about 1.500 experts provides more than 10.000 reviews, the conference being finally attended by 1.500 - 2.000 professionals from all around the world. IEEE ICC is therefore one of the most significant scientific events of the networking and communications community, a must-attend forum for both industrials and academics working in this area.
