Optimal and suboptimal power spectrum estimation techniques

الملخص EN

Optimal and suboptimal power spectrum estimation techniques are reviewed in this paper.

Also, a new optimal spectral estimation technique is proposed.

The optimality criterion is based on noisy pulse responses in the time domain.

The time domain solution also minimizes a practical frequency domain criterion.

The new algorithm is tested against popular spectrum estimation schemes such as Periodia-gram, Blackman-Tukey, Burg, Cadzow, covariance, Music and other suboptimal methods, and compares favorably.

The simulation is done for various cases of signal to noise ratio.
