关于无线信道的多普勒谱 无线信道中的多普勒谱有一种经典谱请解释产生这种谱形状的机理；-1. On the radio channel of the Doppler spectrum (2) wireless channel Doppler spectrum has a classic spectrum (classic spectrum), please explain such a spectral shape of the mechanism

单径或多径瑞利衰落信道仿真，相控阵天线的方向图（切比雪夫加权），从先验概率中采样，计算权重，虚拟力的无线传感网络覆盖，已调制信号计算其普相关密度，是本科毕设的题目，基于chebyshev的水声信号分析，这个有中文注释，看得明白。- Single path or multipath Rayleigh fading channel simulation, Phased array antenna pattern (Chebyshev weights), Sampling a priori prob
