U.S. DIGITAL CELLULAR ERROR-CORRECTION CODING ALGORITHM ON TMS320C5X DSPS

U.S digital cellular terminal designs commonly use programmable digital signal processors (DSPs). All digital cellular transmitters employ conventional and CRC codes to protect against channel-induced errors. Receivers use Viterbi decoders and CRC syndrome checks to verify that the decoded data contains no errors. This document presents examples of error-protection and correction functions for VSELP cellular data and the FACCH channel format. The examples use the 16-bit fixed-point TMS320C5x DSP family.
