本文利用复制方法提出一种新的OVSF码复制生成算法,并在此基础上,研究了非可重排和可重排两种情况下的OVSF码快速分配问题. 利用复制生成的OVSF码字具有明显的异前置性特点,从而可以提高码字分配效率和减小硬件实现复杂度和降低呼叫阻塞率。-In this paper, methods to copy a new copy OVSF code generation algorithm, and on this basis to study the non-rearrangement and rearrangement in both cases the rapid distribution of OVSF code. The use of copy generated OVSF code word with obvious characteristic of different pre-and thus can improve the allocative efficiency of code and reduce the hardware complexity and lower the call blocking rate.
