Abstract
This work applies perfect-shuffle on software defined radio's bit-shuffling blocks, such as puncturer and interleaver, which data alignment issue is also investigated. A demonstration of such algorithm on IEEE 802.11a (WiFi) standard is implemented with Texas Instruments ® intrinsic perfect-shuffle and inverse perfect-shuffle instructions combined with ANSI C on a TMS320 C64x digital signal processor. Simulation results indicate the performance enhancement using perfect-shuffle technique dramatically improved cycle efficiency comparing to a naive one bit per integer implementation.
