Exploiting Slepian-Wolf codes in wireless user cooperation
Rong Lin Hu, Jing Li · 2005
A novel scheme, termed Slepian-Wolf cooperation, is proposed, which exploits distributed source coding technologies in wireless cooperative communication to improve the inter-user outage performance. After motivating the idea, we discuss in detail a simple estimation mechanism, a combined data-syndrome transmission strategy and an optimal joint decoding algorithm. Using low-density parity-check codes as an example, we show that encouraging gains of up to 13 dB for the outage performance and 3.8 dB for the overall performance can be achieved on block Rayleigh fading channels.
