代码说明:

  1)已知2N点实数序列 N=64。用一个64点的复数FFT程序,一次算出 ,并绘出频谱 。 (2)已知某序列 在单位圆上的N=64等分样点的Z变换 。用N点IFFT程序计算 ,绘出图像 。 (1) known 2N-point sequence of real numbers N = 64. With a 64-point complex FFT process, a calculated and mapped the spectrum. (2) known to a certain sequence in the unit circle on the N = 64 sub-samples of the Z transform. N-point IFFT procedures used, the mapped image.)

    由于多径和移动台运动等影响因素,使得移动信道对传输信号在时间、频率和角度上造成了色散,如时间色散、频率色散、角度色散等等,因此多径信道的特性对通信质量有着至关重要的影响,而多径信道的包络统计特性成为我们研究的焦点。根据不同无线环境,接收信号包络一般服从几种典型分布,如瑞利分布、莱斯分布和Nakagami-m分布。(Because multipath and mobile and other sports influence factor, makes mobile channel in transmission in time and frequency signal and Angle caused the dispersion, such as time dispersion, frequency dispersion, Angle dispersion, and so on, thus multipath channel of communication with the characteristics of quality is very important, while the effect of multipath channel (the statistical properties become the focus of our research. According to different wireless environment, receiving signals envelope general subject to several typical distribution, such as Rayleigh distribution, rice distribution and Nakagami-m distribution. )
