A dynamic grouping trasmitter/receiver and control system of remote antenna units and the dynamic grouping method in cdma bunched system

PURPOSE: A transceiver for dynamic grouping of distributed antennas in a CDMA communication system and a control system and a dynamic grouping control method using the same are provided to control transmission signal power of each distributed antenna based on signal strength received from the distributed antennas, thereby smoothly supplying a mobile communication service without deteriorating quality and minimizing interference power. CONSTITUTION: RAUs(Remote Antenna Units)(200_1-200_3) transmit communication data received from a terminal(100), or transmit the communication data to the terminal(100) by communication power received from a central unit(300). The central unit(300) controls to receive the communication data by variable power in the RAUs(200_1-200_3) based on transmission delay received from the RAUs(200_1-200_3). Each of the RAUs(200_1-200_3) consists of transmission delay elements(210) and receiving transmission delay elements(220). The transmission delay elements(210) calculate transmission delay conditions of the central unit(300), and transmit the conditions. The receiving transmission delay elements(220) receive transmission delay data received from the central unit(300).
