| 摘 要： | Log-MAP算法是Turbo码译码算法的一种简化算法，本文针对其所存在的缺点提出了一种改进的算法，即用分段的线性函数对校正函数进行拟合。计算机模拟结果表明，应用此算法后可在不影响性能的情况下，既能简化算法过程，又能使硬件的实现变得更加容易。

| Abstract: | Log-MAP algorithm was a simplified decoding method of Turbo code. In order to overcome its disadvantage, this paper presented an improved method for Log-MAP, in which segment linear function was used to approximate calibration function. Computer analog analysis had shown that the advantages of simplified calculation and hardware convenience could be achieved from this improved method, as well as no negative effect on the performance of algorithm process. |
