PURPOSE:To use efficiently a spread code due to spread spectrum. CONSTITUTION:Stationary equipments 106-108 in the standby state use a control spread code so as to apply inverse spread processing to a reception signal. When a call takes place, a CPU 121 of a master set 102 refers to a memory 122 to select a control code for talking and informs it to a mobile set. Then the communication between the master set 102 and the mobile set is implemented by using the selected control code. |
