A system includes a method for detecting a signal interference in a communication signal of a wireless communication system. An identified source of the signal interference is determined according to an interference profile of a plurality of interference profiles associated with an interference profile library having information that approximates characteristics of the signal interference. The signal interference of the communication signal is mitigated according to an interference parameter associated with the identified source by filtering the communication signal according to the interference parameter.

A SINR measurement of a second base station based on the SINR measurement target is obtained prior to a changing of an amplitude of a portion of a signal of a first base station. A determination is made as to whether the changing of the amplitude of the portion of the signal has reduced a second average SINR measurement of the second base station below a SINR threshold. In response to determining that the changing of the amplitude of the portion of the signal has reduced the second average SINR measurement of the second base station below the SINR threshold, the changing of the amplitude of the portion of the signal is reversed. Other embodiments are disclosed.
