摘要： Provided is dual mode operation by a communicating device in wireless network. The communicating device selects a radio frequency (RF) channel and a physical layer type. The communicating device processes signals received via the selected RF channel based on the selected physical layer type. The communicating device may determine whether a beacon frame has been detected base on the signals that were received via the selected RF channel and processed based on the selected physical layer type. When a frame is not detected, the communicating device may determine a signal energy level for the received signals. The communicating device may establish an association with an existing network based on detection of the beacon frame or the communicating device may transmit an originating beacon frame based on the determined signal energy level.

摘要： A wireless transceiver includes an antenna array that transmits an outbound RF signal containing outbound data to remote transceivers and that receives an inbound RF signal containing inbound data from the remote RF transceivers, wherein the antenna array is configurable based on a control signal. An antenna configuration controller generates the control signal to configure the antenna array to hop among a plurality of radiation patterns based on a hopping sequence. An RF transceiver section generates the outbound RF signal based on the outbound data and that generates the inbound data based on the inbound RF signal. In one configuration, a switching section selectively couples a selected one of the antennas in the array to the RF transceiver section, based on the control signal. In another configuration, the RF transceiver section includes an RF section for each antenna in the array.

摘要： A method for receiving a frame in a high data throughput wireless local area network begins by receiving a preamble of the frame via a channel in accordance with a default receiver filter mask. The processing continues by validating the preamble. The processing continues by, when the preamble is validated, interpreting the preamble to determine a high data throughput channel configuration. The processing continues by reconfiguring the default receiver filter mask in accordance with the high data throughput channel configuration to produce a reconfigured receiver filter mask. The processing continues by receiving a data segment of the frame in accordance with the reconfigured receiver filter mask.

摘要： An apparatus for high data throughput reception in a WLAN includes a receiving module, first and second determining modules, a generating module, and a producing module. The receiving module receives a symbol vector representing M streams of symbols transmitted via a wireless communication channel. The first determining module determines inner coded bits and extrinsic information of the inner coded bits based on the symbol vector, a channel matrix, and inner extrinsic information feedback. The second determining module determines outer coded bits and extrinsic information of the outer coded bits based on the extrinsic information of the inner coded bits, the inner coded bits, and a soft input soft output decoding process. The generating module generates the inner extrinsic information feedback based on the extrinsic information of the outer coded bits. The producing module produces decoded bits based on the outer coded bits.

摘要： A method for generating a preamble of a frame for a multiple input multiple output (MIMO) wireless communication begins by, for each transmit antenna of the MIMO wireless communication, generating a carrier detect field, wherein, from transmit antenna to transmit antenna, the carrier detect field is cyclically shifted. The method continues by, for a first grouping of the transmit antennas of the MIMO wireless communication: generating a first guard interval following the carrier detect field; and generating at least one channel sounding field, wherein, from transmit antenna to transmit antenna in the first grouping, the at least one channel sounding field is cyclically shifted, and wherein the at least one channel sounding field follows the first guard interval. The method continues by, when the MIMO wireless communication includes more than the first grouping of the transmit antennas, for another grouping of the transmit antennas: generating at least one other channel sounding field, wherein, from transmit antenna to transmit antenna in the another grouping, the at least one other channel sounding field is cyclically shifted, and wherein the at least one other channel sounding field follows the at least one channel sounding field; and generating the first guard interval prior to the at least one other channel sounding field.
