Abstract:
A method and device for suppressing an interference signal, the method comprising: performing signal reduction on a received signal of a given cell; performing channel estimation on the signal-reduced received signal of the given cell on the basis of a reference signal of the given cell and a reference signal of a neighboring cell to obtain a precise interference signal; and performing signal suppression on the precise interference signal. In the present application, before acquiring an interference signal, signal reduction is first performed on a received signal of a given cell, and then using a signal obtained by performing the signal reduction on the received signal of the given cell, estimation of interference is performed on the basis of scheduling information of a joint neighboring cell to acquire an accurate interference signal, achieving improved suppression of neighboring cell uplink co-channel interference.

Claim (Index 4):
The method of  claim 3 , wherein performing channel estimation on the rough interference signal according to the reference signal of the neighboring cell to obtain the precise interference signal comprises:\n obtaining the conjugate of the reference signal of the neighboring cell, then multiplying with the rough interference signal to obtain a precise channel frequency-domain response with reference signal eliminated; subjecting the precise channel frequency-domain response to inverse discrete Fourier transform to obtain a precise channel time-domain impulse response; subjecting the precise channel time-domain impulse response to multi-user separation and windows selection denoising to obtain a precise single-user time-domain impulse response; subjecting the precise single-user time-domain impulse response to Fourier transform to obtain a precise channel estimation result of the neighboring cell; subtracting the precise channel estimation result of the neighboring cell from the rough interference signal to obtain the precise interference signal.
