摘要
分析了具有抗多径措施的噪声归一化合并SFH/MFSK接收机在存在部分边带的干扰了多径瑞利衰落信道中的性能,着重研究了多和戏加权因子w对该系统性能的影响。
Analyzes performance of noise-normalization SFH/MFSK Systems with antimultipath measures over a multipath Rayleigh fading channel with partial-band noise jamming, and emphasizes the effect of the multipath weighting factor ω on system performance.Results show that, the optimum weighting factor ω concerns the multipath interference strength diversity number L, modulation order M and channel thermal noise. Bit error rate (BER) can be apparently reduced by weighting moderately, and it decreases by 2 to 3 magnitudes when codes are combined with diversity.
