摘要
提出了一种基于矩特征的信噪比估计算法,并对该算法进行了详细推导。仿真结果表明,该算法在低信噪比条件下也有较好的性能。该算法的计算复杂度低,易于在工程上实现。
A method based on second moments to estimate SNR is introduced. The simulation result shows that the method performs well even in low SNR condition, has low algorithm complexity, and can be implemented easily in practice projects.
