PURPOSE:To obtain the mobile body communication in which a transmission reception information quantity for a telephone signal is reduced. CONSTITUTION:The system employs each radio base station 30 covering each of plural zones and a gate exchange 20 to exchange the communication with each mobile radio equipment 10 using a radio channel with a telephone signal superimposed thereon for the communication with each radio base station 30. Then both the radio base station 30 and the mobile radio equipment 100 store each sample of lots of time piece signals being timewise divisions of the telephone signal in the first stage of the talking and compare each sample of the time piece signals with the stored sample to obtain the coincidence during talking Only the identification signal of the coincident time piece signal is subjected to diversity transmission and the receiver side reproduces the telephone signal based on the identification signal. Since the information quantity to be sent is considerably reduced, the reduced quantity is used for reducing transmission power and the transmission quality is improved by the diversity transmission. |
