ABSTRACT:
A channel estimation section112estimates the states of channels used for pieces of mobile station apparatus (A) and (B), using signals demodulated by radio processing sections110, 111. A best SIR calculation section118calculates coefficients to be used for signal transformation by inverse matrix calculation, using the above channel estimation values by the above channel estimation section112. A signal transformation section119performs linear transformation of transmission signals to the above pieces of mobile station apparatus, using the above coefficients from the above best SIR calculation section118. Radio processing sections120, 121modulates each transmission signal after the above linear transformation for transmission through antennas108, 109, respectively.
