数字图像在时间选择性衰落信道下传输，难以获得满意效果。
The received image is not satisfactory over time-selective fading channel.
接收端的高速运动或者载频的偏移，会引起信道的时间选择性衰落。
Time-selective Rayleigh fading of channels is caused by Doppler shift and carrier frequency offset.
因此在频率选择性衰落信道中，采用分集接收可以改善系统的捕获性能。
Therefore, system acquisition performance can be improved if diversity receiver is adopted for the frequency-selective fading channel.
