The paper presents a novel approach to increase the performance and/or throughput of iterative belief propagation (BP) decoding of low density parity check (LDPC) codes. The proposed approach is based on utilizing the decoder idle time by introducing two queue s: one at the decoder input and the other at the decoder output. At the presence of an input queue, the decoder runs extra iterations beyond...
The paper presents a novel approach to reduce the bit error rate (BER) in iterative belief propagation (BP) decoding of low density parity check (LDPC) codes. The behavior of the BP algorithm is first investigated as a function of number of decoder iterations, and it is shown that typical uncorrected error patterns can be classified into 3 categories: oscillating, nearly-constant, or random-like,...
This paper presents a novel approach for the design and implementation of a simulation platform for evaluating LDPC codes performance. The existing LDPC code simulation tools consume very long time in evaluating the performance of a specific code design. This is due to the intensive number of required computations. This problem is overcome by developing a parallel protocol to distribute the computations...
