Patent abstract

A solution for equalization in a radio receiver is provided. According to the provided solution, equalization with a zero forcing equalization algorithm is improved with frequency domain processing of received information symbols. The frequency spectrum of received information symbols is modified with a calculated frequency domain representation of the radio channel impulse response. Thereafter, the information symbols having the modified frequency spectrum are filtered with a zero forcing filter having the filter coefficients calculated through a zero forcing algorithm.
