Full-duplex communication system

摘要

In a TDM communication system (100), full duplex communication is provided for two communication units(104) and (105) which communicated communication messages through a repeater (102). Communication messages transmitted from the communication units (104) and (105) are combined in the repeater (102) to produce a combined communication message. The repeater (102) transmits the combined communication message to the communication units (104) and (105). The communication units (104) and (105) remove from the combined communication message the communication the previously transmitted communication message so as to recover the communication message from the other communication unit.
