METHOD AND APPARATUS FOR TRANSMISSION WITH INTERFERENCE SUPPRESSION

摘要

The estimation section (112) uses the signal demodulated by a wireless section (110) and a wireless section (111) to estimate the state of the circuits that mobile station (A) and mobile station (B) use. An SIR optimizer (118) determines a coefficient for use in signal conversion by means of an inverse matrix using the circuit estimate provided by the estimation section (112). The signal converter (119) carries out linear conversion of the signals to be transmitted to the mobile stations using the coefficient obtained from the SIR optimizer (118). The wireless section (120) and the wireless section (121) modulate the converted signals and transmit them through an antenna (108) and an antenna (109), respectively.
