Abstract
In this paper, an initial phase estimation of single-tone signal is proposed based on the Fast Filter Bank (FFB). With the help of characteristics of FFB such as narrower transition width and higher stopband attenuation and low complexity, the proposed initial phase estimation based on FFB is more accurate than that of based on FFT, and the phase estimation can be also estimated without correction regardless of whether there is deviation of frequency. Simulation explains the better performance of estimating initial phase based on FFB and the method can be extended to estimate other parameters such as magnitude of the single-tone signal in a similar way.
