RECEIVING DEVICE OF RADIO TELECOMMUNICATION

摘要

a transmitter transmitting by spreading the bandwidth of an orignal signal to transmit; a receiving means receiving a complex signal inputted by mixing the spread signal transmitted from the transmitter and a noise signal from the external; an amplitude limit means to attenuate the noise component signal by compressing the noise signal having an amplitude level higher than the amplitude of the spreaded original signal; and an inverse spread means narrowing the bandwidth of the original signal and broadening the bandwidth of the noise signal simultaneously by inverse-spreading the output of the amplitude limit means.
