A method and device for detecting a signal of an LTE uplink system in an interference condition. The method comprises: receiving baseband signals of M receiving antennas, and after fast Fourier transform, conducting demapping to obtain frequency-domain baseband signals; extracting a DMRS inserted in a received signal of each antenna, and then, calculating a channel gain hof each receiving antenna; combining the baseband signals and the channel gains of the M receiving antennas to obtain a signal matrix Yand a gain matrix H; calculating an interference noise covariance matrix Ron each subcarrier; conducting interference pre-processing on a received signal on each combined subcarrier to obtain the received signal (1) and the channel gain (2) after the interference pre-processing, where D=R; and according to (3), conducting frequency-domain balancing on the received signal after the interference pre-processing.
