Abstract (in Japanese) (See Japanese page) 
(in English) This paper presets merits and demerits of frequency division duplexing (FDD) using the carrier frequency swapping which we previously proposed aiming at the decrease in feedback signals for packet radio access techniques. In the carrier frequency swapping method for FDD, two duplexers are necessary. Hence, we propose transceiver structure applying antenna isolation by a set of transmit and receive antennas and analog self-interference canceller (SIC). We also consider the effect for decreasing overhead of feedback signals by using the carrier frequency swapping for FDD based on the feedback signal structures for Long Term Evolution (LTE).
