一种无线信道状态估计新算法

A New State Estimation Algorithm of Wireless Channel

在实践中,Nakagami衰落信道下的信道状态的估值算法在很多最优化的信号处理技术中都是必需的。该文根据高阶统计量的分析提出一种简单有效的信噪比估值算法,而且首次提出了Nakagami衰落信道下的全盲信道状态估值算法,同时通过进行信道状态估值对turbo码译码精度的灵敏性仿真测试证明了新算法的有效性。

In practice, the channel state in Nakagami fading needs to be estimated for many optimum signal processing techniques. A new algorithm is put forward on the basis of the higher order statistical analysis, which is simple and effective, furthermore, a new all-blind channel state estimation algorithm in Nakagami fading is presented for the first time, and its validity is proved by simulations.
