Abstract:
1. A receiver used in a spread spectrum communication system, comprising: a base band signal power-detecting unit for detecting power of a base band signal which is obtained by analog to digital (A/D, hereinafter) converting an output of a quadrature demodulator, wherein said quadrate demodulator quadrature demodulates an intermediate frequency signal outputted from an automatic gain control (AGC, hereinafter) amplifier, a symbol rate signal power-detecting unit for detecting power of a symbol rate signal which is obtained by despreading said base band signal, an error rate-detecting unit for detecting an error rate of a desired wave on a basis of said symbol rate signal, and an AGC amplifier-controlling unit for controlling a gain of said AGC amplifier depending on outputs of said base band signal power-detecting unit, said symbol rate signal power-detecting unit and said error rate-detecting unit.
