改进的水声信道载波恢复盲均衡算法

Modified Blind Equalization Algorithms for Carrier Recovery of Underwater Acoustic Channel

为提高修正的常数模算法(MCMA)的收敛速度,进一步降低算法的剩余均方误差,提出了3种改进的盲均衡算法,既保留了MCMA算法载波恢复的功能,又不同程度地提高了MCMA算法的收敛速度。最后通过水声信道仿真,对这些算法的性能进行了验证和比较。

To speed up the convergence of the Modified CMA and reducing its residual mean squared error,three cartier recovery blind equalization algorithms are presented in this paper. These algorithms may not only recover cartier phase,but also outperform the Modified CMA in terms of convergence speed and residual mean squared error. The performance of new algorithms are demonstrated and compared by underwater acoustic channel simulations.
