PURPOSE:To provide the spread spectrum communication equipment which avoids a problem of distance to realize the full duplex communication in the time division multiplex communication system even in the case of communica tion limited to a single frequency band. CONSTITUTION:In the network where one master equipment 1-2 and plural slave equipments 1-1 are connected like a star, the master equipment 1-2 controls the time of simultaneous transmission to all slave equipments 1-1 and the time of simultaneous reception from all slave equipments 1-1. The master equipment 1-2 has a function to inform the slave equipments that the master equipment is in course of transmission at the time of transmission from the master equipment, and each slave equipment 1-1 has a function to not only switch transmission/ reception of them based on information which indicates that the master equipment is in course of transmission but also control the power of transmission output. |
