PROBLEM TO BE SOLVED: To provide a radio equipment for an adaptive array radio base station that can adopt a small-sized reception terminal with low power consumption and high reception quality. SOLUTION: An adaptive array reception section 1030 extracts a signal received from a desired terminal 1100 from signals received by an array antenna 1010 and a frequency offset compensation unit 1032 calculates a frequency offset. In this case, a frequency offset inverse compensation section 1042 applies phase rotation to a transmission signal from a transmission signal modulation section 1040 on the basis of an inverse compensation amount (transmission state phase rotation amount) θOUT and an adaptive antenna transmission section 1044 transmits the resulting signal from the array antenna 1010 to a terminal 1100. The terminal 1100 applies synchronization detection to the signal without recovering a carrier. |
