| 摘 要： | 在相位和频偏等信道参数未知条件下，Turbo码的解码性能急剧恶化。本文将存在频偏的接收信号等效为高斯白噪声中的正弦信号，提出了一种基于MUSIC算法的信道参数估计算法，并在Turbo码解码中对信道参数进行联合迭代估计。仿真结果表明基于MUSIC算法的Turbo码联合迭代解码的良好性能。

| Abstract: | If phase and frequency offset are unknown to the receiver, the performance of Turbo code decoding decreases seriously. The received signals for systems having uncertain frequency offset are assumed to be equivalent to a sine in the white Gauss noise. The MUSIC algorithm is used to estimate the channel parameters. Then the parameters estimation is joined to Turbo decoding. Simulations demonstrate the good performance of the joint iterative estimating and decoding. |
