    摘要: A multiple input multiple output (MIMO) RF transceiver system includes a plurality of RF transceiver ICs, a crystal, and master oscillation coupling. Each of the plurality of RF transceiver ICs includes crystal oscillator circuitry. Crystal oscillator circuitry of the first RF transceiver IC and a crystal are operable to produce a master oscillation. Master oscillation coupling couples the master oscillation produced by the first RF transceiver IC to the at least one other RF transceiver IC. In one embodiment, the master oscillation is passed from the first RF transceiver IC to each other transceiver RF ICs. In another embodiment, the master oscillation is used to produce a slave oscillation at a second RF transceiver IC and subsequent RF transceiver ICs produce there own slave oscillation based upon a slave oscillation received from a prior RF transceiver IC.

    摘要: A method for generating a preamble of a frame for a multiple input multiple output (MIMO) wireless communication begins by, for each transmit antenna of the MIMO wireless communication, generating a carrier detect field, wherein, from transmit antenna to transmit antenna, the carrier detect field is cyclically shifted. The method continues by, for a first grouping of the transmit antennas of the MIMO wireless communication: generating a first guard interval following the carrier detect field; and generating at least one channel sounding field, wherein, from transmit antenna to transmit antenna in the first grouping, the at least one channel sounding field is cyclically shifted, and wherein the at least one channel sounding field follows the first guard interval. The method continues by, when the MIMO wireless communication includes more than the first grouping of the transmit antennas, for another grouping of the transmit antennas: generating at least one other channel sounding field, wherein, from transmit antenna to transmit antenna in the another grouping, the at least one other channel sounding field is cyclically shifted, and wherein the at least one other channel sounding field follows the at least one channel sounding field; and generating the first guard interval prior to the at least one other channel sounding field.

    摘要: A method for multiple protocol wireless communications begins by determining protocols of wireless communication devices within a proximal region. The method then continues by determining whether the protocols of the wireless communication devices within the proximal region are of a like protocol. The method continues by, when the protocols of the wireless communication devices within the proximal region are not of a like protocol, selecting a protocol of the protocols of the wireless communication devices within the proximal region based on a protocol ordering to produce a selected protocol. The method continues by utilizing the selected protocol by the wireless communication devices within the proximal region to set up a wireless communication within the proximal region.
