COMMUNICATION TERMINAL EQUIPMENT AND RADIO COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To display superior reception without deteriorating channel estimation precision in transmission diversity applying closed loop transmission diversity. SOLUTION: At the time of closed loop transmission diversity, communication terminal equipment calculates a phase correction for compensating the influence of the phase rotation of transmission diversity from known feedback information, corrects the reception signal of a communication channel based on the phase correction and corrects a channel estimation value based on the phase correction.
