<p>A narrow band interference suppression method is disclosed. The method comprises: performing channel estimation using a received pilot symbol in a time-frequency unit; calculating the noise-interference power of the pilot symbol based on the channel estimation result, and taking the noise-interference power of the pilot symbol as the noise-interference power of the data symbol in the time-frequency unit; performing combination estimation under the noise-interference of multiple antennae using the channel estimation result and the noise-interference power of the data symbol; performing data decoding with the bottom noise power when it is determined that the estimation result of the noise-interference power is less than the setting threshold value, otherwise performing data decoding with the current estimation result of the noise-interference power. A device for realizing such interference suppression method is also disclosed. Such solutions can implement better interference suppression on account of the solutions perform the interference estimation for the noise signals of the data signals in advance. And, the calculation of the method is simple.</p> |
