A SWP- (Sub-Word Parallelism-) based RAKE receiver for a Wideband Code-Division Multiple Access (WCDMA) mobile station is optimized to perform channel de-rotation and data combining. The RAKE receiver comprises SIMD (Single Instruction, Multiple Data) instructions, which can perform a complex multiplication for a channel de-rotation in a single cycle. The SIMD instructions can also perform a complex addition for data combining in a single cycle. Optimization of the RAKE receiver reduces power consumption and costs, enhances performance, and provides extensibility for next-generation architectures.
