其编码数据格式能够很好地应用于图像和视频的统计编码中，在保持编码效率的同时，很大程度地提高编码在信道传输中的纠错能力。
The pdfs to which these codes correspond are well matched to statistics of image and video data, thus enabling an increase in robustness to channel errors with no penalty in coding efficiency.
理论上，CP的长度等于信道冲激响应的记忆长度，较长的CP大大降低了DSL系统的数据传输效率。
In theory, the length of the CP was equal to the memory length of the impulse response of the channel.
