    Abstract: A method for generating a preamble of an Orthogonal Frequency Division Multiplexed (OFDM) data frame for a multiple input multiple output (MIMO) wireless communication includes determining at least one system condition preamble format parameter. When the system condition preamble format parameter satisfies a first preamble format parameter a preamble having a first preamble format is formed. When the system condition preamble format parameter satisfies a second preamble format parameter, a preamble having a second preamble format is formed. Further, when the system condition preamble format parameter satisfies a third preamble format parameter, a preamble having a third preamble format is formed. The first, second, and third preamble formats differ based upon their lengths, fields, and modulation formats of a high throughput signal field.

    Abstract: 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.

    Abstract: Communication device architecture for in-place constructed LDPC (Low Density Parity Check) code. Intelligent design of LDPC codes having similar characteristics there between allows for a very efficient hardware implementation of a communication device that is operative to perform encoding of respective information bit groups using more than one type of LDPC codes. A switching module can select any one of the LDPC codes within an in-place LDPC code for use by an LDPC encoder circuitry to generate an LDPC coded signal. Depending on which sub-matrices of a superimposed LDPC matrix are enabled or disabled, one of the LDPC matrices from within an in-place LDPC code matrix set may be selected. A corresponding, respective generator matrix may be generated from each respective LDPC matrix. Selection among the various LDPC codes may be in accordance with a predetermined sequence, of based operating conditions of the communication device or communication system.

    Abstract: A Wireless Local Area Network (WLAN) system based upon peer-to-peer communications. A wireless terminal for peer-to-peer communications acts either as a WLAN master or as a WLAN slave. When the wireless terminal acts a master, the wireless terminal undertakes mastering duties that include transmitting a beacon interval in the frame cycle. When the wireless terminal is not tethered to a power source, mastering duties alternate according to a round-robin WLAN mastering cycle, wherein the wireless terminal acts the WLAN master during at least one frame cycle and acts the WLAN slave during other frame cycles to conserve an untethered power source of the wireless terminal.

    Abstract: A radio frequency transmitter includes a baseband transmit processing module, a mixing module, a power amplifier, a transmit power sense module, and a transmit power control module. The baseband transmit processing module is operably coupled to encode outbound data into outbound baseband signals in accordance with one of a plurality of encoding protocols. The mixing module is operably coupled to convert the outbound baseband signals into outbound radio frequency signals. The power amplifier is operably coupled to amplify the outbound RF signals prior to transmission to produce amplified outbound RF signals. The transmit power sense module is operably coupled to sense the amplified outbound RF signals to provide a transmit signal strength indication (TSSI). The transmit power control module is operably coupled to adjust gain of the baseband transmit processing module, the mixing module, and/or the power amplifier based on the TSSI and the particular encoding protocol used to produce the baseband signals.
