Abstract:
A spread-spectrum communication apparatus transmitting and receiving an information signal in a high-frequency-band, said apparatus comprising:(a) a radio frequency (RF) receiver for receiving and amplifying the high-frequency spread-spectrum modulated by the information signal; (b) a de-spreader for reproducing the modulated signal from the high-frequency spread-spectrum modulated signal; (c) an analog demodulator for reproducing the information signal from the modulated signal; (d) a received signal strength indicator (RSSI) for detecting a strength of the modulated signal reproduced by said de-spreader, and for feeding back a resultant detection to said de-spreader; and (e) a limiter circuit disposed at a stage prior to said de-spreader for limiting an amplitude of an input signal such that the modulated signal does not exceed a saturating level of said RSSI.
