Comparison of Gaussian channel with Rayleigh fading channel over LDPC-DPC transmission scheme
Subash Shree Pokhrel, Moon Ho Lee · 2007
The dirty paper channel model indicates that lossless precoding is theoretically possible at any signal-to-noise ratio (SNR). In this paper, we propose a transmission scheme for dirty-paper coding using Low density parity check (LDPC) codes and compare the performance between Gaussian and Rayleigh fading channels. The simulation results show that LDPC codes are good coding schemes over Gaussian channel using LDPC-DPC transmission scheme in multiuser communication systems.
