Abstract :
Joint detection is a high complexity module in TD-SCDMA system. This paper analyzes the selection of algorithm, and presents an overview of optimization methods for the selected algorithm based on general purpose processors (GPPs) It includes look-up-able (LUT), Single Instruction Multiple Data (SIMD) and Intel Integrated Performance Primitives (Intel IPP) Library. The results of timing test illustrate that with utilizing these methods, the joint detection module in TD-SCDMA system can achieve huge benefits in real-time performance.
