用One-Bit谱相关算法改进的FSM算法

Modification of FSM Algorithm with One-Bit Spectrum Correlation Algorithm

随着循环谱的深入研究,循环谱计算方法的实时性日益重要。FSM是一种循环谱频域平滑算法,为了解决消耗内存资源大、缺乏实时性的问题,给出了改进的实现方法,并用软件进行了验证。仿真的结果表明,文中提出的算法能节省大量运算时间和存贮空间。

With the intensive research on the cyclic spectrum, the real-time computation of cyclic spectrum is more and more important. FSM is based on frequency-smoothed method for cyclic spectral correlation. For the lack of real-time computation and the waste of memory resource, a modified method is introduced and validated by using software. Simulation results prove that the proposed algorithm can save much computation time and memory.
