0N-ROAD TRANSMISSION SYSTEM AND ON-ROAD RECEPTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an on-road transmission system and an on-road reception system capable of providing multi-station communication without requiring the installation construction of lines in large scale from a central base station to respective transmitting stations. SOLUTION: This system is provided with plural transmitting stations 2 for transmitting the signals of the same OFDM modulated contents into the same cell with the radio wave of the same frequency. The transmitting station 2 is composed of at least one master transmitting station 2a and slave transmitting stations 2b other than the master transmitting station 2a, the slave transmitting station 2b receives a radio wave radiated from the master transmitting station 2a or other slave transmitting station 2b through an antenna 41, repeats/ amplifies that radio wave and transmits it through an antenna 44 into the cell again. Thus, a radio frequency signal is supplied to each transmitting station 2 while using the simple distribution means of the repetition of the radio wave and since each transmitting station 2 transmits the radio wave into the cell on the basis of this signal, the line for supplying the radio frequency signal to the transmitting station 2 is not required except for the master transmitting station 2a.
