RADIO COMMUNICATION SYSTEM, RADIO TRANSMITTER, AND RADIO RECEIVER

摘要

PROBLEM TO BE SOLVED: To provide a simple and low-cost radio communication system wherein its frequency-diversity is so realized effectively even when using such a high-frequency band as a millimeter wave as to prevent any signal interruption. SOLUTION: The radio communication system has a radio transmitter 61 and a radio receiver 62. The radio transmitter 61 at least has an IF-signal generating portion 78 for modulating an intermediate-frequency band by an input signal 63, a signal distributing portion 64 for performing the distributions of the signal fed from the IF-signal generating portion 78, and a plurality of signal transmitting portions 65 for so converting into a radio-frequency band the signals distributed in the signal distributing portion 64 as to transmit radio- frequency-band conversion signals. The radio receiver 62 for so receiving the radio-frequency-band conversion signals as to obtain again the receiving signal of the intermediate-frequency band. COPYRIGHT: (C)2003,JPO
