Abstract
A general total least squares (GTLS) solution for linear prediction to estimate closely spaced sinusoids is presented. A frequency weighted prediction error approach is introduced. Experimental results show tha t the GTLS solution based on the frequency weighted prediction error c an give a robust performance even in very low SNR.
