CA 2331430

The present invention relates to a demodulation structure and method for downconverting and demodulating a digitally modulated signal S, witii a local oscillator means tor pro~~idin~ a local oscillator siunal S_ a miXe.r means for mixing said local oscillator signal S,o and said di~itally modulated signal S, in order to obtain a mixed signal, a lowpass filter means for lowpass tiltering the mixed signal from the nlixer means and an analoa-to-digital convtrtinu means for conve-rtino the tiltcred sign.d trom the lowpass filter means into a downconvCrte.d anci demodulated didital sional S,, whereby the local oscillator signal is set in espect to the modulated digital si~nal so that the downconverted and demodulatcd di;ital si~n;:rl output from t.he analo--to-di-ital convertinv, means comprises two serially arranged inform<ition parts. Tht present in%-,ention provides a dcn1odulation str- ucture and me.thoci with a vr.rv simple structure anci esscntiall%iniproved arnhlitude and phase imhalances.
