Abstract: Single-site localization of wireless emitters in a rich multipath environment is presented. The localization method is based on exploiting the spatio-temporal characteristics of the multipath signals, referred to as the multipath fingerprint, as captured by the base station antenna array. The method is applicable to all modern communication techniques such as WiFi and LTE and to any rich multipath environment in indoors and outdoors.

Abstract: 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).

Abstract: 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.
