摘要
文中介绍了W CDM A上行码片级协处理DSP软件系统的构成,接着对该软件系统代码优化的问题进行了分析,然后提出了几种有效的代码优化方法,最后描述了对利用上行DPCCH导频进行信干比估计函数进行单元优化的过程,并给出了仿真环境下该函数代码优化的测量结果。
In this article, firstly the structure of the software system of the uplink chip rate assistant DSP is introduced. After that, some efficient optimization methods for C code are presented. Finally, the process of the unit optimization for the function of computing SIP, （signal to interference ratio） using the pilot in the uplink DPCCH （dedicated physical control channel）is described, and the simulation test results of the code optimization for the computing SIR function are also given.
