标准化变量
We first point out the limitations of currently standardized IS 95 variable bit rate scheme. Then we analyze the orthogonal characteristics between the Walsh functions of different periods, and present the method of properly choosing Walsh function for each channel in order to support multi rate transmission.
文中首先指明了现有IS-95系统多速率传输的局限性,然后通过分析不同周期离散Walsh函数的正交特性,指出如何通过适当分配各个用户信道的Walsh码,达到支持多速率业务的目的。
