参数时变信道的频率选择性和时变性。BPSK符号率=512b/s,采样率=16个采样/s,a1(t) 和a2(t) 为多普勒带宽=16Hz。结果为符号间干扰。
Parameters of time-varying channel frequency selectivity and time-variant. BPSK Symbol Rate = 512b/s, sampling rate = 16 samples/s, a1 (t) and a2 (t) as the Doppler bandwidth = 16Hz. The results for the inter-symbol interference. (2009-12-24, matlab, 2KB, 下载42次)
