Patent ID: 7095995

Claim:
A diversity receiver comprising: a plurality of antennas for receiving radio signals subjected to orthogonal frequency division multiplex; delay circuits for adding pretermined fixed delay times to received RF signals in such a manner that a predetermined fixed delay time difference is given between any two received RF signals among the received RF signals simultaneously received with said antennas; a mixer for synthesizing a received RF signal received with said antenna not coupled to said delay circuit and received RF signals added with the fixed delay times by said delay circuits; a tuner for frequency-converting a RF signal in a predetermined band synthesized by said mixer to obtain an intermediate frequency signal; and a demodulator for demodulating the intermediate frequency signal supplied from said tuner to obtain a digital signal, wherein said delay circuits add the fixed delay times to the received RF signals simultaneously received by said antennas in such a way that the fixed delay time difference between any two received RF signals is the reciprocal or more of a bandwidth allocated to one subcarrier of orthogonal frequency division multiplex.
