Receiver applicable to eliminating interference

The invention discloses a receiver applicable to eliminating interference. The receiver comprises a channel estimator used for estimating the user channel characteristics or user and interference channel characteristics; a filter coefficient calculator used for calculating the linear filter coefficient and the equivalent channel impulse response after passing a filter; a linear filter for restricting interference; and a non-linear detector used for eliminating the remaining interference among signals. The receiver with the structure can be compatible with a single antenna and double antennas even multiple antennas; and the low-complexity characteristic can be applicable to various modulation manners. The purpose of adopting the receiver with the structure is to guarantee that various types of receivers or receivers working under different modulation manners can adopt the same receiver structure while guaranteeing the excellent performance, thus bringing convenience for manufacturers to enhance the development speed and reduce the manufacturing cost and simultaneously being beneficial to the receiver to be compatible with various modulation manners.
