As one of the standards of 3G mobile communication systems, the TD-SCDMA system has some performance advantages which are different from the other two main standards because of its TDD duplex. It can improve the quality of the asymmetry transmitting service. Dynamic Channel Allocation (DCA) technology is one of the key technologies in the TD-SCDMA system, which has been putted forward based on the real conditions and the development trend of the communication service, can not only allocate the channel resources more reasonably but also improve the tense states of the spectrum resources. This main contribution in the paper is given an improved algorithm which can reduce the proportion of data lose and make better in the utilization of the wireless spectrum.
