Abstract
Disclosed is a MIMO receiving apparatus in which a residual interference calculation unit () inputs noise-suppressed frequency domain channel estimation values, output from FFT units (--to-M-N), equalizing weights calculated by a weight calculating unit (), equalized signals from equalization processing by an equalization filter () and reference signals generated by reference signal generating units (-to-M) to calculate a residual interference, and the likelihood correction units (-to-M) receive time domain equalized signal from the IDFT units (-to-M) and the residual interference calculated by the residual interference calculation unit () to correct the likelihood of the equalized signal (FIG.).
