摘要： Embodiments of the present invention relate to methods and systems for simultaneous communication with multiple wireless communication devices. In some embodiments, a method for simultaneous communication with multiple wireless communication devices includes receiving, using a plurality of antennas at a first wireless station, a plurality of packets, comprised of orthogonal frequency division multiplexing (OFDM) wireless signals, transmitted simultaneously from a plurality of other wireless stations wherein each of the simultaneously transmitted packets includes a plurality of frequency tones, frequency domain transform the received packets, grouping frequency domain transform outputs for each subcarrier, determining a difference between subcarrier groups formed over different sample sets, and determining a set of weights for each subcarrier, wherein the weights are selected such that the first wireless station can at least one of detect or demodulate the received plurality of packets.

摘要： Described herein is an apparatus for inclusion in a station of a wireless network, and a method implemented in a station of a wireless network. The method includes wirelessly receiving data via each of a plurality of antennas (703and 705), the data corresponding to a packet of information transmitted from a remote station, sampling the received data corresponding to the received packet to form data samples for each of the antennas, and determining a measure of signal quality from samples of the received data for each of the antennas. The method further includes selecting (1003) one of the plurality of receive antennas as the antenna for receiving from the remote station according to the determined measure of signal quality.

摘要： A method and an apparatus in a first wireless station of a network transmitting to a second wireless station through OFDM signals. The first station includes multiple antennas (113, 115) and a receive and a transmit signal path per antenna. Each receive signal path includes a discrete Fourier transformer (445, 447) and each transmit signal path includes an inverse discrete Fourier transformer. The method includes determining channel estimates (449, 451) for each tone and each receive path while receiving from the second station, determining transmit weights (475) to transmit to the second station, tone-by-tone weighting a signal for transmission to the second station to produce weighted tone sets for each transmit signal path, and transmitting the weighted tone sets (417, 419).
