The power spectrum has played a vital role in the signal processing domain, thus the estimation about power spectrum has brought people's enormous attention. This paper mainly discusses the minute variance power spectrum estimation method, acquires the effi cient estimation of autocorrelation matrix based on least-squares method. Simulation results prove the approach is feasibility.
