摘要
介绍了一种串行级联环卷积编码连续相位调制技术,给出了基于外信息传输(EXIT)图的串行级联环卷积编码连续相位调制系统的收敛性能分析。通过EXIT图可以找出不同串行级联环卷积编码连续相位调制系统的收敛门限。仿真结果表明:串行级联环卷积编码连续相位调制系统的参数不同,收敛的门限也不同;收敛的门限越低,性能越好。
Serially concatenated continuous phase modulation using convolutional code over rings is introduced in the paper,and the convergence analysis of the system based on extrinsic information transfer(EXIT) chart is presented too.The convergence thresholds of different systems can be find by using EXIT chart.The simulation result shows that the convergence thresholds of the system with different parameters are different,and the lower the threshold,the better the performance.
