A wireless access point coherently receives signals transmitted from client devices and from interfering devices, measures noise and interference capture samples from the received signals, and computes a characterization of noise plus interference. Receive gains and threshold levels are adjusted based on the computed noise plus interference characterization. A set of weights for an interference suppression spatial filter are calculated from the measured noise and interference capture samples and used to produce a filtered signal by spatially filtering the received signals such that interference is spatially nulled in the filtered signal. The method may also include setting PHY parameters at the wireless access point based on the computed noise plus interference characterization. In some embodiments, a protection transmission is transmitted from the wireless access point, requesting connected client devices to suspend transmissions during a specified time period.

Enhancing WLAN performance in the presence of interference

A method for communication over a wireless local area network (WLAN) includes receiving uplink signals from a plurality of stations in the WLAN. Responsively to the uplink signals, a set of the stations is selected for inclusion in a spatial multiplexing group. Downlink signals are transmitted simultaneously to the stations in the set using spatial division multiplexing (SDM).

WLAN capacity enhancement using SDM

A method for communication includes receiving signals transmitted over the air by first and second mobile stations on a common frequency channel in a wireless packet network, the signals carrying first and second data packets transmitted by the first and second mobile stations, respectively, the first and second data packets comprising respective, first and second headers. 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.
