An Implementation of Low Power and Low Complexity TURBO

A modified TURBO algorithm is proposed with efficient operation.This algorithm remarkably reduces the amount of hardware of the TURBO decoder,where the scale of decoder memories can be reduced to the half memories required by conventional algorithms.Based on the modified TURBO algorithm,a new Add-Compare-Select (ACS) unit is designed.The simulation results show that the area and power consumption of proposed ACS unit are 32.7% and 26.8% of conventional ACS units,respectively.
