Abstract:
A time-division multiple access radio communication device comprising:a receiving-data buffer portion to receive data from plural sources by using a carrier wave and to store the received data; a unique word detecting portion to detect a unique word from the received data to determine a synchronous point as a starting point for timing adjustment; a timer portion for the timing adjustment by counting time from the point that the unique word is detected at the unique word detecting portion; a cyclic redundancy check (CRC) calculating portion to check errors in the received data; and a send-data buffer portion to store the data to be sent; wherein an acknowledgement data generating portion is further provided, the acknowledgement data generating portion checking errors in the received data based on a calculation result at the CRC calculating portion, and when the data are assumed to be error-free, the acknowledgment data generating portion generating acknowledgement data and sending to a send-data processing path, while at all other times sending stored data from the send-data buffer portion to a send-data path by switching.
