Abstract
The present invention is a method and system for estimating interference. Packet characteristics of relevant packets within the channel at a given point in time may be processed. For example, a power level, occupied frequency and corresponding time references may be accumulated and stored for each relevant packet within the channel at a given point in time. As each packet is processed for demodulation, the channel samples, at which interference occurred, may be appropriately weighted based on the packet characteristics. Advantageously, the nature of the interfering channel traffic may be measured to properly de-weight the interference in a computationally efficient manner.
