Abstract :
A new method is presented for wide-band frequency estimation with sub-Nyquist sampling by using two independent sampling channels at the different rates. With low cost of hardware and moderate computation, the proposed method is not sensitive to the relative amplitude and phase errors of both channels. Simulations demonstrate the capabilities of the algorithm
