RADIO COMMUNICATION DEVICE, RADIO COMMUNICATION METHOD, AND RADIO COMMUNICATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To avoid a deterioration in estimation accuracy and achieve a stable and high degree of signal separation in a radio communication device separating a transmission signal and a reception signal.

SOLUTION: A radio communication device separates a transmission signal and a reception signal, and comprises: an antenna for transmitting and receiving a signal; transmission means for transmitting a transmission signal via the antenna; propagation path estimation means for estimating the phase amplitude response of a signal having sneaked from a transmission side into a reception side in a propagation path estimation section; replica generation means for generating a wraparound signal replica on the basis of the estimated phase amplitude response and the transmission signal; subtraction means for subtracting the wraparound signal replica from a reception signal received via the antenna; and receiving means for performing reception processing of the reception signal after the subtraction. The radio communication device further comprises: auto-correlation calculation means for calculating the worst value of an auto-correlation characteristic of the transmission signal within a prescribed delay time; and propagation path estimation section determination means for determining that a section where the worst value of the auto-correlation characteristic is equal to or less than a threshold value is to be the propagation path estimation section.
