针对经典频移滤波运算复杂度大,工程应用难于实现的问题,研究了利用多级分解维纳滤波的降秩滤波方法和硬件实现过程中的优化方法,设计实现了一套基于DSP的信号分离方法测试平台,并对算法的硬件实现性能进行了测试分析。
There must be a huge amount of computations and difficult to apply to project in optimum FRESH filter.To solve the problem this paper describes a reduced-rank method based on MSWF and a optimization method for hardware implementation.Then a test model to verify the algorithm performance which implements in DSP is constructed.
