Multi-antenna system interference cancellation apparatus and method

Embodiment of the present invention disclose interferes with one multi-antenna system elimination method and apparatus, the method comprising: according to the received on the receiving antenna baseband signal, the channel estimation the transmission signal on the antenna array and a downlink channel acquisition of multiple transmit cross-correlation matrix generating equalization coefficients; interference canceller processing the baseband signal according to the equalization coefficient. Apparatus comprising: a coefficient generation module, configured to receive based on the receiving antenna baseband signal, a channel estimate correlation matrix generated equalization coefficients transmission signal on the antenna array and obtaining downlink channel transmitted in a plurality; interference canceling module, for the coefficients for the equalization of the baseband signal for the interference cancellation process. The present embodiment eliminates the downlink channel transmitting the generated interference correlation between the transmitted signals on a plurality of antennas, the effect of improving the balance and improve the performance of the receiver.
