摘要： A method for asymmetrical MIMO wireless communication begins by determining a number of transmission antennas for the asymmetrical MIMO wireless communication. The method continues by determining a number of reception antennas for the asymmetrical MIMO wireless communication. The method continues by, when the number of transmission antennas exceeds the number of reception antennas, using spatial time block coding for the asymmetrical MIMO wireless communication. The method continues by, when the number of transmission antennas does not exceed the number of reception antennas, using spatial multiplexing for the asymmetrical MIMO wireless communication.

摘要： A wireless local area network (WLAN) transmitter includes a baseband processing module and a plurality of radio frequency (RF) transmitters. The baseband processing module is operably coupled to process data by scrambling the data in accordance with a pseudo random sequence to produce scrambled data. The processing of the data continues by selecting one of a plurality of encoding modes based on a mode selection signal. The processing of the data continues by encoding the scrambled data in accordance with the one of the plurality of encoding modes to produce encoded data. The processing of the data continues by determining a number of transmit streams based on the mode selection signal. The processing of the data further continues by converting the encoded data into streams of symbols in accordance with the number of transmit streams and the mode selection signal. A number of the plurality of RF transmitters are enabled based on the mode selection signal to convert a corresponding one of the streams of symbols into a corresponding RF signal such that a corresponding number of RF signals is produced.

摘要： A decoder includes an interface and a processing module. The interface receives first data, redundant data of the first data, second data, redundant data of the second data, and combined redundant data. The processing module decodes the first data based on the redundant data of the first data, decodes the second data based on the redundant data, of the second data and verifies the decoding of the first and second data. When the first data is decoded successfully and the second data is not, the processing module encodes the first data to produce a second redundant data of the first data, determines a second redundant data of the second data based on the combined redundant data and the second redundant data of the first data, decodes the second data based on the second redundant data of the second data, and verifies the decoding of the second data.

摘要： Methods and systems for distributed infrastructure for streaming data via multiple access points. Aspects of one method may include apportioning multimedia information among a plurality of transmitting devices based on feedback channel information received from a destination receiving device by, for example, a transmission controller device. The transmitting devices may transmit the multimedia information to the destination receiving device. A transmitting device that may not be apportioned multimedia information may transmit a probing signal. The destination receiving device may generate feedback channel information for a transmitting device, for example, based on the multimedia information or the probing signal received from the respective transmitting device. The apportioning of the multimedia information may be dynamically adjusted based on updated feedback channel information received from the destination receiving device.

摘要： Aspects of a method and system for redundancy-based decoding of voice content in a wireless local area network (WLAN) system are provided. A WLAN receiver may determine whether a decoded portion of a received packet comprises voice content and may select a redundancy-based decoder to decode a remaining portion of the packet when voice content is detected. The redundancy-based decoder may be a Viterbi decoder. The redundancy-based decoder may be selected to decode a determined number of subsequent packets or to decode subsequent packets for a determined amount of time. After decoding the remaining portion of the packet and any subsequent packets, the WLAN receiver may select a standard Viterbi decoder to decode additional received packets. The WLAN receiver may generate at least one signal to select the redundancy-based decoder and the standard Viterbi decoder.
