<P>PROBLEM TO BE SOLVED: To provide a device capable of reducing reception errors while suppressing increase in interference and reducing in amount of data, and a program to be applied to the device. <P>SOLUTION: A base station 20 comprises a prospective point specifying unit 34 for specifying a reference signal point which is the nearest to a reception signal point as a first prospective point, a reception error estimating unit 33 for determining possibility whether the first prospective point responding to the reception point is wrong or not, a second prospective DB 35 for memorizing the reference signal point except for the first prospective point as a second prospective point about the reception signal point responding to the first prospective point determined as the possibility of errors to be existing by the reception error estimating unit 33, an error detecting unit 37 for detecting whether a demodulated signal to be acquired using a value corresponding to the first prospective point is wrong or not, and a bit value changing unit 38 for changing a value responding to the first prospective point to a value responding to the second prospective point when the demodulated signal is to be detected as wrong by the error detecting unit 37. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
