PROBLEM TO BE SOLVED: To provide a wireless communication system which allows for enhancement of reception performance, by reducing the influence of setting error of modulo lattice size, in non-linear MIMO communication.SOLUTION: In a mobile terminal performing wireless communication of a signal, modulated by an orthogonal frequency division multiplex system, by a non-linear MIMO system of vector perturbation, a lattice position estimation unit 2209 estimates the lattice position of a signal in expansion signal constellation, a channel decoding unit 2218 performs error correction for a signal, obtained by demodulating a modulo operation signal for a predetermined constellation, depending on a likelihood value weighted based on the estimated lattice position. |
