A Telemetry TPC Decoding Algorithm Based on Simplified Soft Information Iteration
【摘要】 针对遥测TPC译码算法中Chase2算法译码流程复杂,处理接收信号存在较大时延的问题,提出简化软信息迭代的遥测TPC译码算法。该算法通过减少迭代译码次数和优化软信息更新方式,在提高译码速率、减少资源消耗的同时,纠错能力损失小于1 dB。仿真结果表明,改进算法减少了译码算法运算量,提高了译码实时性,降低了存储要求。
【Abstract】 Aiming at the problems of complex decoding process of Chase 2 algorithm in telemetry TPC decoding algorithm and large delay in processing received signals, a telemetry TPC decoding algorithm based on simplified soft information iteration was proposed. The algorithm adopted the method of reducing the number of iterative decoding and optimizing the soft information update mode, which could improve the decoding rate and reduce the resource consumption, while the error correction ability loss was less than 1dB. Simulation results showed that the improved algorithm reduced the computation of decoding algorithm, improved the real-time performance of decoding, and reduced the storage requirements.
