连续导频正弦波通过存在Doppler频移的快衰落信道复模型（基带等效模型）的构造(Continuous pilot frequency sine wave by the presence of Doppler shift fast fading channel model (complex baseband equivalent model) structure)

Decimation reduces the original sampling rate for a sequence to a lower rate, the opposite of interpolation. The decimation process filters the input data with a lowpass filter and then resamples the resulting smoothed signal at a lower rate.
