摘要:
基于连续相位编码(continuous phase encoder,CPE)的记忆与递归特性,结合LDPC码及随机交织器,构建LDPCC-CPM系统模型.针对传统接收机中解调器与译码器之间缺少信息共享的弊端,引入Turbo迭代检测机制,提出一种基于软输入软输出(soft-input soft-output,SISO)算法的迭代检测方法,探讨主要参数对系统性能的影响,为实际应用中系统参数的选择提供依据.加性高斯白噪声(additive white Gaussian noise,AWGN)信道下的仿真结果表明,在低信噪比条件下,与传统串行接收机相比,所设计的迭代接收机能有效改善系统的收敛性,降低地板效应出现的概率,提高系统检测误比特率的性能.
Abstract:
A model of LDPCC-CPM system based on the memorial and recursive properties of the continuous phase encoder (CPE) was presented. This model is integrated with low-density parity-check code (LDPCC) and interleaver. The Turbo iterative detection mechanism based on soft-input soft output (SISO) algorithm was to improve the information exchange between demodulator and decoder in the traditional receiver. The effects of major parameters on LDPCC-CPM system and the design reference of parameter selection were discussed in detail. The simulation results have demonstrated that the proposed receiver can effectively improve the convergence of the system and reduce the probability of error-floor over an additive white Gaussian noise (AWGN) channel with low signal-to-noise ratio. Therefore, the BER performance of the system is advantageous over the traditional receiver.
