摘要
针对智能抄表系统中数据传输方式造成的数据不稳定、可靠性低的情况,提出了一种基于电力线载波通信(Power Line Carrier Communication,称PLC)传输技术的全局耦合准循环低密度奇偶校验(Globally Coupled Quasi-Cyclic Low-density Parity-check)GC-QC-LDPC码的编码方案。数值仿真结果表明,在AWGN信道和BPSK调制下,GCQC-LDPC码在智能抄表系统数据传输中有较好的纠错性能,因而有工程应用价值。
In this paper,In view of the unstable data and low reliability caused by the data transmission method in the intelligent meter reading systems,We propose a Globally Coupled Quasi-Cyclic Low-density Parity-check(GCQC-LDPC)code based Power Line Carrier Communication(PLC)coding scheme.Numerical results show that the proposed GC-QC-LDPC codes have good performance over the AWGN channel with BPSK modulation,thus what we proposed is valuable in practical engineering.
