摘要： An iterative decoder for use in a WLAN includes an inner decoder/detector, a first subtraction module, a deinterleaving module, an outer decoder, a second subtraction module, an interleaving module, and a determining module. The inner decoder/detector determines inner coded bits and extrinsic information of the inner coded bits from symbol vector based on a channel matrix and inner extrinsic information feedback. The first subtraction module subtracts the inner extrinsic information feedback from the extrinsic information of the inner coded bits. The deinterleaving module deinterleaves the output of the first subtraction module to produce deinterleaved inner extrinsic information. The outer decoder determines outer coded bits and extrinsic information of the outer coded bits from the deinterleaved inner extrinsic information. The second subtraction module subtracts the deinterleaved inner extrinsic information from the extrinsic information of the outer coded bits. The interleaving module interleaves the output of the second subtraction module to produce the inner extrinsic information feedback. The determining module produces decoded bits based on the outer coded bits.

摘要： An adaptive communication device includes a transceiver that communicates with a first remote communication device in a millimeter wave frequency band in accordance with a first protocol. The transceiver generates conflict detection signals based on signals received from a second remote communication device that communicates in accordance with a second protocol. A conflict detection module detects communication by the second communication device based on the conflict detection signals and generates a model trigger signal in response thereto. A conflict modeling module responds to the model trigger signal by generating idle prediction data based on the conflict detection signals, wherein the idle prediction data predicts an idle period in the communications by the second remote communication device. A transmission control module generates transmit control signals based on the idle prediction data, wherein the transceiver times transmissions sent to the first remote communication device based on the transmit control signals.

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： 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 feeding back transmitter beamforming information from a receiving wireless communication device to a transmitting wireless communication device includes a receiving wireless communication device receiving a preamble sequence from the transmitting wireless device. The receiving wireless device estimates a channel response based upon the preamble sequence and then determines an estimated transmitter beamforming unitary matrix based upon the channel response and a receiver beamforming unitary matrix. The receiving wireless device then decomposes the estimated transmitter beamforming unitary matrix to produce the transmitter beamforming information and then wirelessly sends the transmitter beamforming information to the transmitting wireless device.
