WLAN CAPACITY ENHANCEMENT BY CONTENTION RESOLUTION

摘要

A method for communication includes receiving signals transmitted over the air by first and second mobile stations (22, 24) on a common frequency channel in a wireless packet network (20), the signals carrying first and second data packets (40, 42) transmited by the first and second mobile stations, respectively, the first and second data packets comprising respective, first and second headers (46). The received signals are processed so as to identify the first header. Responsively to the identified first header, signal values corresponding to at least a portion of the first data packet are reconstructed, and the reconstructed signal values are subtracted from the received signals so as to produce a modified signal. The modified signal is processed in order to identify the second header. The first and second data packets are demodulated using the identified first and second headers.
