Doppler frequency estimation system and method |
摘要 |
A Doppler frequency estimation system includes a basis projector, a polynomial generator and an extreme value determinator. The basis projector receives and projects multiple channel sampling signals to a set of orthogonal bases to thereby generate multiple channel correlation vectors. The polynomial generator is connected to the basis projector in order to produce a target polynomial based on the channel correlation vectors, an estimated channel-envelope-to-noise-plus-interference power-ratio and a channel-envelope power. The extreme value determinator is connected to the polynomial generator in order to determine an extreme value of the polynomial and output a frequency corresponding to the extreme value as an estimated Doppler frequency.
