摘要

设计采用连续相位频移键控(CPFSK)调制的多支路两跳相位前传(PF)协作系统需要确定支路数、调制系数等参数，确定这些参数的通常解决方法是使用非常耗时且低效的计算机仿真，而一种高效的解决方案是理论分析法。提出了一种时间选择性瑞利衰落信道上，中继节点考虑两根天线选择、目的节点采用最大比合并(MRC)分集接收和鉴相检测的 CPFSK 调制的 PF 协作系统平均误比特率(ABER)的半解析表达式分析理论。CPFSK 调制 PF 协作系统的 ABER 数值计算结果和仿真结果相吻合，证明了利用获得的 CPFSK 调制ABER分析理论可用于设计PF协作系统。

Abstract

Design of multi-branch dual-hop phase-only forward(PF)cooperative systems with continuous phase frequency shift keying(CPFSK)modulation needs to determine the number of branch and modulation index.The usual solution of determining the above parameters is the time-consuming and inefficient computer simulation.An efficient solution of determining these parameters is theoretical analysis method.Semi-analytical expressions for the average bit error rate(ABER)of multi-branch dual-hop PF cooperative systems in conjunction with discrimination detection CPFSK over time-selective Rayleigh fading channels was presented.Two cases with and without antenna selection at the relays and maximum-ratio combining(MRC)receive diversity at the destination were considered.The simulation results show that numerical calculation results and simulation results for the ABERs of PF，discrimination detection

CPFSK cooperative systems are consistent and show that the above ABER theory results of CPFSK cooperative systems can be used to design PF cooperative systems.
