摘要： A method for wireless communication between stations of differing protocols begins by determining whether protocols of target stations of a wireless communication are different than a protocol of a source station. The method continues by, when at least one of the target stations has a different protocol than the protocol of the source station, determining whether the wireless communication is a direct wireless communication or an indirect wireless communication. The method continues with the source station transmitting a frame to an access point, wherein the frame is formatted in accordance with the protocol of the source station, when the wireless communication is the indirect wireless communication. The method continues with the access point converting the frame into at least one alternate frame based on the protocol of the at least one of the target stations having the different protocol. The method continues with the access point transmitting the at least one alternate frame to the at least one of the target stations.

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.

摘要： LDPC (Low Density Parity Check) coding and interleaving implemented in multiple-input-multiple-output (MIMO) communication systems. As described herein, a wide variety of irregular LDPC codes may be generated using GRS or RS codes. A variety of communication device types are also presented that may employ the error correcting coding (ECC) using a GRS-based irregular LDPC code, along with appropriately selected interleaving, to provide for communications using ECC. These communication devices may be implemented to in wireless communication systems including those that comply with the recommendation practices and standards being developed by the IEEE 802.11n Task Group (i.e., the Task Group that is working to develop a standard for 802.11 TGn (High Throughput)).

摘要： A wireless transceiver includes a phased array of antennas, that transmit 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 phased array of antennas is configurable based on a control signal. An antenna configuration controller generates the control signal to configure the phased array of antennas 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 antenna of the phased array of antennas to the RF transceiver section, based on the control signal. In another configuration, the RF transceiver section includes an RF section for each antenna of the phased array of antennas.

摘要： A transmitting MIMO wireless device transmits a training sequence to a receiving MIMO wireless device. The receiving MIMO wireless device estimates a channel response based upon the training sequence, determines an estimated transmitter beamforming unitary matrix and a transmit path quality matrix, and then transmits some/all of these parameters to the transmitting MIMO wireless device. The transmitting MIMO wireless device receives these components and determines a modulation to be employed for each of a plurality of data streams. The transmitting MIMO wireless device transmits a data frame to the receiving MIMO wireless device that includes a short training sequence, a long training sequence, a signal field with demodulation control signals, and a data payload for each of multiple data streams. According to one embodiment of the signal field, the signal field indicates a number of data streams of the data frame and a modulation employed for each data stream. The signal field may include additional information, such as whether beamforming is employed for the data frame.
