Space hopping receiving system and received radio-waves estimation method

Abstract

A receiving system or a received radio-wave estimation method is provided that can maintain received field strengths at a nearly uniform level under multipath conditions. The antenna switch 41 can select outputs of four antennas at high speed (where n=4). The high-frequency amplifier 42 amplifies the output of the antenna switch 11 and the demodulator 42 demodulates amplified signals. The matched filter bank 45, surrounded with chain lines, receives a demodulated signal, for example, the I-phase component. In the matched filter bank 45, the phase shifter φ shifts respective signals output from four delay elements (r1, r2, r3, and r4). The adder (Ka, . . . , Kp) synthesizes the phase-shifted signals and then supplies the maximum matched output to the maximum level selector 46.
