摘要: In this paper, a novel algorithm is proposed, which focus on estimating the period of independent source and number multi-component signal that recorded by single antenna overlapped both in time frequency domain. The method adopts technique changing single-channel recording vector into virtual multi-channel measurement matrix, then using Singular Value Decomposition (SVD) decompose matrix. By measure singular value ratio (SVR) spectrum can be got. searching peaks SVR, components estimated effectively, based correlation coefficient between each obtain useful SVD, original will simulation results demonstrate effectiveness algorithm. What more, high accuracy under low signal-noise-ratio (SNR) condition also illustrated simulation.
