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 can select outputs of four antennas at high speed. The high-frequency amplifier amplifies the output of the antenna switch and the demodulator demodulates amplified signals. The matched filter bank, surrounded with chain lines, receives a demodulated signal, for example, the I-phase component. In the matched filter bank, the phase shifter shifts respective signals output from four delay elements. The adder synthesizes the phase-shifted signals and then supplies the maximum matched output to the maximum level selector.
