And then, it presents INTRA refresh based on feedback, inserting re-synchronous markers, using Sequence Number field of RTP, which are suitable to the channel character of CDMA 1X. Experiment results of the method are presented.

• 然后结合CDMA 1X的信道特点,提出了基于反馈的帧内刷新,插入重同步标识和利用RTP协议Sequence Number域进行差错控制的方法,并测得实验结果。
