摘要： A method for generating a preamble of a frame for a wide-bandwidth channel wireless communication begins by generating a legacy carrier detect field. The method continues by generating a channel sounding field, wherein the channel sounding field includes a plurality of tones within the wide-bandwidth channel, wherein a first set of the plurality of tones corresponds to tones of a legacy channel sounding field. The method continues by generating a legacy signal field, wherein, in time, the legacy signal field follows the channel sounding field, which follows the legacy carrier detect field.

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： Within a local region, information may be communicated between two or more wireless multimode communication devices (WMCD) comprising 60 GHz band and lower frequency band wireless interfaces. Spatial relationships between devices may vary. The 60 GHz interface may handle location determination operations and data transfers. The lower frequency band may support WPAN, WLAN and may handle coordination of communications and data transfers. The WMCDs may be coupled with a network. Antennas may be directional. Moreover, the spatial orientation of the antennas may be dynamically modified or swept across a specified angle. Furthermore, intelligent and/or adaptive antenna systems may be utilized. The WMCDs may utilize a position and/or time reference system to aid in location determination operations.

摘要： Method and system encodes a signal according to a code rate that includes a ratio of uncoded bits to coded bits. An outer Reed-Solomon encoder encodes the signal into codewords. An interleaver converts the codewords into bits of frames for wireless transmission. An inner encoder executes a convolutional code to generate an encoded signal. The encoded signal is transmitted over a plurality of subcarriers associated with a wide bandwidth channel. The convolutional code is punctured and code states are added by the inner encoder to improve the code rate.

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 first device wirelessly transmits and/or receives swept 60 GHz beacon signals to and/or from other devices. Beacon signals indicate angle of reception and/or relative direction with respect to other devices. Knowing reception angle and/or relative direction enables beamforming of adaptive and/or steered antennas for communication. 60 GHz beacons are swept over one or more angles. Identity information, configuration information, timing information and/or spatial information are communicated via 60 GHz beacons. Control and/or coordination information are transmitted and/or received. Reception angle, relative direction and/or distance between devices are determined based on 60 GHz beacons. Adaptive and/or steered antennas used for communication are initialized and/or undergo beamforming for 60 GHz, based on the angle, direction and/or distance between devices. Devices are mobile and/or stationary. Devices comprise mobile stations, base stations, wireless phones, access points, set-top-boxes, computers, game consoles, video servers, video recorders, video playback devices, residential gateways and internet browsing devices.

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.
