Abstract
A channel equalization and tracking apparatus and method and a receiver. The apparatus includes: a Fourier transforming unit configured to transform a received time-domain signal into a frequency-domain signal; a compensating and equalizing unit configured to perform phase compensation and frequency-domain equalization on the signal outputted by the Fourier transforming unit by using one time of multiplication according to time delay information and an equalizer coefficient; a deciding unit configured to decide the equalized signal; and a channel tracking unit configured to track a channel according to the signal outputted by the Fourier transforming unit and an error signal obtained by the deciding unit. With embodiments of the present disclosure, not only complexity and hardware demands of the whole system are lowered, but also performance of the system is not affected.
