摘要： Embodiments of a wireless transceiver are provided. Embodiments can be used in multiple-input-multiple-output (MIMO) wireless transceivers. In an embodiment, radio control signal bundles are provided as direct parallel interconnects between digital signal processing modules and the radio module of the wireless transceiver to enable a precise low-latency control of radio functions. In another embodiment, a separate physical line is provided to control each radio setting of the radio module, thereby enabling simultaneous real-time control of any number of radio settings. In a further embodiment, the various digital and analog components of the wireless transceiver are integrated within a single chip of the same process technology.

Aspects of the method may include determining a signal quality metric for each of a plurality of signal paths, modifying the signal quality metric for each of the plurality of signal paths, and selecting at least one signal path based on at least one modified signal quality metric. At least one of the signal paths may be cycled through and the signal quality metric may be biased and/or increased and/or decreased for each of the plurality of signal paths by a fixed amount and/or by a predetermined amount. The signal quality metric may also be dynamically changed for each of the plurality of signal paths.

摘要： A programmable transmitter generates a frame in a frame format according to one of a plurality of operating modes using a frame structure table storing a respective frame format for each of the operating modes. The transmitter includes a frame structure engine that receives a mode selection signal indicative of a select operating mode, and accesses the frame structure table to determine the frame format of the select operating mode. The frame structure engine produces a control signal to a frame generator to control the generation of a frame in the frame format of the select operating mode.

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.
