The invention provides an interference reconstruction rejection combining method of a multi-reception antenna. In consideration of the mobile communication of the multi-reception antenna, the invention provides a new multi-antenna combining method, namely, interference reconstruction rejection combining (IRRC). The method comprises the following steps: firstly, estimating an expecting signal from a receiving signal which is not modulated and contains interference and noise by a tradition method, and modulating and demodulating to obtain the estimating value of the expecting signal with the noise removed; ejecting an expecting signal from the receiving signal to obtain reconstructed interference signals; and finally, calculating the weight required by the expecting signal by using covariance matrix of the interference signal to recover the expecting signal. In comparison with the traditional interference rejection combining method using signal approximate interference and noise signal, the method is more accurate, so that the recovered expecting signal has high accuracy and excellent performance.
