Deeply-pipelined high-throughput LDPC decoder architecture
Abstract:
Certain aspects of the present disclosure generally relate to methods and apparatus for decoding low density parity check (LDPC) codes, and more particularly to a deeply-pipelined layered LDPC decoder architecture for high decoding throughputs. Accordingly, aspects of the present disclosure provide techniques for reducing delays in a processing pipeline by, in some cases, relaxing a dependency between updating bit log likelihood ratios (LLRs) and computing a posteriori LLRs.
