摘要

本文研究了turbo解码器性能对噪声分布不匹配的敏感性，提出了一种简单的在线估计接收信号各块未知噪声分布的方法。对于高斯噪声和拉普拉斯噪声，所提出的程序导致解码器性能与噪声分布确切已知的情况相当(在0.1 dB内)。

On the robustness of turbo decoders

This paper investigates the sensitivity of turbo decoder performance to mismatch of the noise distribution and proposes a simple on-line procedure for estimating the unknown noise distribution from each block of received signal. For Gaussian and Laplacian noise, the proposed procedure leads to decoder performances which are comparable (within 0.1 dB) to the case where the noise distribution is known exactly.
