Decoding apparatus for code division multiple access system, has turbo decoder that repeat decoding process until Reed Solomon decoder that decodes output of turbo decoder outputs error correction completion signal

摘要

#CMT# #/CMT# A Reed Solomon (RS) decoder (150) decodes a signal decoded by a turbo decoder (120), and outputs a completion signal on completing an error correction process. A controller (140) controls the turbo decoder to repeat the decoding process for specific number of times until the completion signal is output. #CMT# : #/CMT# An independent claim is also included for decoding method. #CMT#USE : #/CMT# Decoding apparatus used in wireless digital communication system such as code division multiple access (CDMA) communication system and wide band CDMA (W-CDMA) communication system. #CMT#ADVANTAGE : #/CMT# Enables to perform decoding efficiently with optimized error correction performance within short period in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows the block diagram of the decoding apparatus. 110 : input buffer 120 : turbo decoder 140 : controller 150 : RS decoder 170 : output buffer 180 : memory.
