RADIO COMMUNICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To solve a problem wherein individual information channels can not by synchronously detected in a radio system to use a common pilot in an array antenna. SOLUTION: Array weights are switched in a chip rate and the transmitting direction of pilot signals is switched. In such a case, the order of switching is known. Therefore, the pilot signals to be transmitted to respective sub-sectors can be separated and receiving of both individual traffic signals and a common paging signal can be synchronously detected by using the pilot signals.
