一种用于cdma2000的新的Turbo码迭代译码方案

A New Iterative Decoding Algorithm of Turbo Codes for cdma2000

由于 Ｔｕｒｂｏ码优异的纠错性能使得其在第三代移动通信（３Ｇ）系统中倍受重视。无论是ＷＣＤＭＡ还是。ｃｄｍａ２０００都将其作为候选的信道编码方案，并且将其列为３Ｇ的核心技术之一。本文将 ｃｄｍａ２０００中的 Ｔｕｒｂｏ码和同等译码复杂度的卷积码进行比较，给出了在加性白高斯噪声信道和瑞利衰落信道中的仿真结果。

Due to their excellent performance of error correcting, turbo codes have raised great interest in the third generation mobile communication system. They are introduced as not only the selected coding schemes , but also one of the key techniques. In this paper, the turbo codes for cdma2000 is compared with the convolutional codes of equal decoding complexity, and simulation results in AWGN and Rayleigh fading channel are shown.
