Abstract :
In this paper, we investigate the design of low density parity check (LDPC) codes for the additive white Gaussian noise channel with binary interference causally known at the encoder. Relying on the the extrinsic information transfer chart, we propose a systematic approach to designing LDPC codes for this type of channels. Corroborating numerical examples demonstrate superior performance of our design method.
