Quantized multiple sinusoids signal estimation algorithm

Abstract

A precise and efficient quantized multiple sinusoids signalestimation algorithm is presented. For different initial conditionsobtained using classical spectral estimation algorithms the finalsolution of our algorithm is not unique. We start to minimize anonlinear cost function. The accuracy of the initial values ofiterations has a large influence on the speed of convergence. Aniterative process is performed to reduce the cost function. Algorithmstops when quantization conditions are satisfied. Our algorithm iscomputationally efficient.
