Designing Very Good Low-Density Parity-Check Codes for the Gilbert-Elliott Channel

It has been shown using density evolution (DE) that joint estimation-decoding strategies have excellent performance for regular lowdensity parity-check (LDPC) codes in the GilbertElliott (GE) channel. However, DE is computationally intensive, and is therefore not suitable as a tool in searching for good degree sequences for irregular LDPC codes. In this… CONTINUE READING
