Abstract
Methods of reducing interference in wireless communications in a communications system are provided. A wireless communications signal is received within a frequency band. The wireless communications signal includes a desired component and an undesired interference component. The interference component may be caused by, for example, communications by another component of the communications system using frequencies in the frequency band. The received communications signal is converted to a frequency domain representation. Frequencies of the interference component of the frequency domain signal are identified. At least some of the identified frequencies of the interference component of the frequency domain signal are attenuated to generate an interference attenuated frequency domain signal. The interference attenuated frequency domain signal is converted to an interference attenuated time domain signal.
