摘要

本文在移动硬件平台的图形处理单元(gpu)上使用并行计算，探讨了加速信念传播(BP)和基于BP的LDPC码解码算法。为了在有限的译码时间内获得最佳的纠错性能，对BP译码算法进行了不同的改进。找到了译码算法、数字精度和计算资源的可能组合。测量了每种发现组合的纠错性能。针对DVB-T2/S2(16200,7200)码采用LDPC编码的数据传输系统，找到了译码算法、数字精度和计算资源的最佳组合。

Parallel LDPC decoder implementation on a mobile GPU

In this paper we explore acceleration of the belief propagation (BP) and BP-based algorithms for decoding LDPC codes, using parallel computation on graphics processing units (GPUs) for mobile hardware platform. Different modifications of BP decoding algorithm are considered in search for best error correction performance in limited decoding time. Possible combinations of decoding algorithms, number precision and compute resources were found. Error correction performance for each found combination was measured. Best combination of decoding algorithm, number precision and compute resource was found for data transmission system with LDPC coding for DVB-T2/S2 (16200, 7200) code.
