There is provided a method of receiving a transmitted signal over a time-varying channel. The method includes: obtaining a received symbol signal in frequency domain based on the transmitted signal; performing a first channel estimation based on the received symbol signal to obtain a plurality of first estimated BEM coefficients; performing a first equalization based on the received symbol signal and the plurality of first estimated BEM coefficients to obtain a plurality of first detected source symbols; and performing one or more rounds of a second channel estimation and a second equalization. Each round includes: performing the second channel estimation based on the received symbol signal and a plurality of detected source symbols to obtain a plurality of second estimated BEM coefficients; performing interference removal based on the received symbol signal, the plurality of detected source symbols and the plurality of second estimated BEM coefficients to obtain an interference reduced symbol signal infrequency domain; and performing the second equalization based on the interference reduced symbol signal and the plurality of second estimated BEM coefficients to obtain a plurality of second detected source symbols. There is also provided a corresponding receiver, and a system for wireless communication over a time-varying channel including the receiver.
