Receiver capable of removing both intersymbol interference and frequency offset.

摘要

In a receiver responsive to a reception signal subjected to an intersymbol interference and a frequency offset, the reception signal is delivered to a matched filter (23) having a filter characteristic matched with a transmission path and filtered into a filter output signal accompanied by the frequency offset. The filter output signal is sent to a frequency offset estimation circuit (25) to produce an estimation signal representative of an estimation value of the frequency offset. An equalizer (24) is supplied with the estimation signal and a selected one of the reception signal and the filter output signal to equalize the frequency offset and the intersymbol interference.
