Abstract:
1. A method for estimating a level of contribution of an interference to a performance metric in a wireless network, comprising: establishing, by a processor, the performance metric, wherein the performance metric comprises a bit error rate; determining, by the processor, a first cumulative distribution function of the performance metric associated with a first time interval and a second cumulative distribution function of the performance metric associated with a second time interval, wherein the first time interval is associated with a time period during which network usage is low as compared to the second time interval, and the second time interval is associated with a time period during which network usage is high as compared to the first time interval, wherein a cumulative distribution function comprises a percentage of call samples during a given time interval that have a bit error rate that is greater than or equal to a given bit error rate of a received signal quality range of a plurality of received signal quality ranges; producing, by the processor, an estimate of the level of contribution of the interference to the performance metric in the second time interval, by subtracting the first cumulative distribution function of the performance metric associated with the first time interval from the second cumulative distribution function of the performance metric associated with the second time interval, wherein the interference comprises a co-channel interference; and reporting, by the processor, the estimate of the level of contribution of the interference to the performance metric in the second time interval.
