| 摘 要： | 本文研究频率选择性相关Nakagami衰落信道上采用最大比合并(MRC)分集接收的正交频分多路复用M进制正交幅度调制(OFDM-MQAM)系统.使用矩生成函数(MGF)方法和高斯超几何函数、Appell超几何函数或Lauricella函数,推导任意衰落参数频率选择性相关Nakagami衰落信道上MRC分集接收的OFDM-MQAM系统的误符号率(SER)性能,获得了OFDM-MQAM误符号率的一个新的解析表达式.数值计算结果阐明了多径路径数、Nakagami衰落参数和信道脉冲响应抽头间的相关系数对OFDM-MQAM误符号率性能的影响.

| Abstract: | We investigate an orthogonal frequency-division multiplex(OFDM) system with two-branch maximal ratio combining(MRC) receive diversity and M-ary quadrature amplitude modulation(MQAM) signals over frequency selective correlated Nakagami-m fading channels in this paper.Using the well-known moment generating function-based analysis approach,we present new closed-form formulas for the exact average symbol-error rate(SER) of OFDM-MQAM system over correlated Nakagami-m fading channels with arbitrary fading index.W... |
