提出了一种改进的TURBO码算法,该算法改进了传统算法的路径度量的运算和可靠度的运算,可以显著地减少TURBO解码器使用的硬件资源,存储器的使用是传统算法的一半。根据改进的算法,该文还提出了一种新的加比选运算单元,综合结果和功耗分析显示,新的ACS单元面积和功耗分别是传统ACS单元的32.7%和26.8%。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.
