摘要
导出了中上衰落信道中l支路等增益分集合成器输出信噪比的互补概率分布函数的无穷级数。分析了匹配滤波器接收机在合并器和不同衰落参数下的误码率。同时考虑相干相移键控和差分相干相移键控。研究了支路间增益不平衡对信噪比概率分布和误码率的影响。得到了移频键控的相干和非相干接收的误码率结果。本文还研究了增益不平衡对FSK调制的影响。结果表明,即使双合成器分支间的增益不平衡为-20 dB (k=0.01),广义衰落模型(m=1)的非分集实例仍有相当大的改进。
Analysis of signal-to-noise ratio distributions and bit error rates for equal gain diversity systems on generalized fading channels
An infinite series for the complementary probability distribution function of the signal-to-noise ratio at the output of L-branch equal-gain diversity combiners in Nakagami fading channels is derived. The bit error rate for a matched-filter receiver is analyzed for the combiner and different fading parameters. Both coherent phase-shift keying and differential coherent phase-shift keying are considered. The effects of gain unbalance between branches on the probability distribution of the SNR and on the bit error rates are investigated. Bit-error-rate results are also obtained for coherent and noncoherent reception of frequency-shift keying. The effects of gain unbalances on FSK modulations are also investigated. It is shown that, even with -20 dB (k=0.01) gain unbalance between the branches of a dual combiner, there is still a considerable improvement over the nondiversity instance for the generalized fading model (m=1).<>
