摘要： 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.

摘要： A method for receiving data packets in a communication network comprising scanning a channel for a preamble during an acquisition search window, detecting the preamble during the acquisition search window, assigning a reception acquisition search window for receipt of a data packet including a data preamble and a data portion, coordinating the transmission of the data packet with the reception acquisition search window, detecting the data preamble during the reception acquisition search window, and initiating receipt of the data portion upon detection of the data preamble.
