单通道小样本信号频率估计算法
Frequency estimation algorithm of small sample single channel signal
摘要
Abstract
A frequency estimation algorithm based on MUSIC was prososed for signal-channel small sample signal ,which analysed the receptive signal and the relation between the discrete sample period and the array element spacing of uniform linear array (ULA) ,and then the new Toeplitz matrix could be presented .The signal subspace and noise subspace could be acquired by performing eigenvalue de-composition of the matrix ,and the M USIC algorithm could be used to estimate the signal frequency accurately on the condition of small sample through single channel .Simulation results show that the proposed method is more effective than the fast Fourier transform (FFT ) .关键词
