Paper Abstract

The ADCP (Acoustic Doppler Current Profiler) technique is the current hot topic of measuring the water velocity. Further more, the frequency estimation algorithm is critical for it. A novel frequency estimator-ELMS for a single complex sinusoid in complex white Gauss noise is proposed. The estimator needs less data than conventional FFT (Fast Fourier Transform) algorithm. The results indicate that the robust algorithm can estimate the spectrum value efficiently when the SNR=0DB.
