Abstract

PURPOSE:To improve a noise-proof characteristic by generating other station's signal components by sum and difference operation between the receiving signal and the delay signal and by eliminating these components from the receiving signal by subtraction. CONSTITUTION:The spread spectrum signal received by receiving antenna 30 is input to other station's signal generation unit 11 to generate other station's signal components. The output signal from other station's signal generation unit 11 is subjected to amplitude limit in limiter 12 and is subjected to level adjustment in amplifier 14 because the output signal has an irregular amplitude, and other station's signal components are eliminated from the receiving signal by subtracting circuit 18. Consequently, the noise-proof characteristic is improved because other station's components functioning as noise are eliminated.
