RADIO DATA COMMUNICATION SYSTEM

摘要

PURPOSE:To attain data communication at a predetermined error rate or below by reducing the effect of interference from other channels. CONSTITUTION:A timing control section 30 outputs a timing control signal synchronizing transmission slot and a reception slot of master sets 201-20N with each other, and a channel assignment section 40 outputs a polling information representing a slave station to be polled. A TDD control section 11 segments the transmission slot and the reception slot based on the timing control signal and a polling control section 12 makes hand-shake to publicate a polling command in the transmission slot to a relevant slave station based on polling information and to input reception data in the reception slot.
