Serially-concatenated LDGM codes for correlated sources over Gaussian broadcast channels |
Abstract | ||
|---|---|---|
We propose a superposition scheme, based on the use of serially-concatenated LDGM codes, for the transmission of spatially correlated sources over Gaussian broadcast channels. The messages intended for each receiver are independently encoded using the same code. In this manner, a strong degree of correlation is kept between the encoded sequences, which are then modulated with different energies and symbolwise added. By properly designing the encoding process, simulation results show that our proposed scheme easily outperforms the suboptimal theoretical limit assuming separation between source and channel coding. |
