摘要:
在N-Nakagami信道下,研究了结合切换驻留合并(SSC)与选择合并(SC)的移动无线传感器网络系统的平均符号误码率(ASEP)和中断概率(OP)性能.基于矩生成函数(MGF)的方法,推导了系统采用相移键控调制(PSK)、正交幅度调制(QAM) 、脉冲幅度调制(PAM)等的ASEP的精确表达式;同时,也推导出了系统中断概率( OP)的精确闭合表达式,然后对不同系统条件下的性能做了数值仿真,验证了理论分析结果的正确性.仿真结果表明:随着分集支路数、衰弱系数的增加,衰弱因子的减小,系统的ASEP和OP性能得到了很好的改善.
Abstract:
On the basis of N-Nakagami fading channels，the average symbol error probability ( ASEP) andoutage probability ( OP) of mobile wireless sensor network system employing switch-and-stay combining( SSC) and selection combining ( SC) are investigated in this paper. Based on the moment generating function(MGF) approach,the exact ASEP expressions are derived for several modulation schemes，including phaseshift keying ( PSK ),quadrature amplitude modulation ( QAM ),and pulse amplitude modulation ( PAM).The exact closed-form OP expressions are also presented. Then the ASEP and OP performance under differentconditions is evaluated through numerical simulations,and the accuracy of the analytical results is verified.The simulation results showed that: the ASEP and OP performance is improved with the diversity branches andthe fading coefficient increased ,while the fading factor decreased.
