    摘要: Apparatuses and methodologies are described that coordinate multiple wireless communication protocols within a mobile device. A single mobile device can contain multiple communication components (e.g., a Bluetooth component, an IEEE 802.11b/g component). To prevent interference and possible loss of data, one communication component may be prevented from transmitting or receiving data packets while the other communication component is either transmitting or receiving. The components may be coordinated by a central controller located in the mobile device. Alternatively, the communication components may exchange messages to determine transmission or reception priority. In addition, one communication component may monitor the status of the other communication component to determine unused communication slots.

    摘要: A system and method of flexible channel allocation in an ultra wideband frequency hopping communication system is disclosed. In one embodiment, a method includes communicating radio signals through rapidly switching among a band group 6 according to a hopping pattern. The method also includes scanning the ultra wideband spectra to determine the band group 6 based on the hopping pattern of the radio signals.In another embodiment, a method includes scanning ultra wideband spectra to eliminate any frequency band of the ultra wideband spectra from a list of available frequency bands when the any frequency band is currently used, selecting a band group in combination of two or more frequency bands to communicate radio signals with an optimal transmission power and/or maximum range, and communicating the radio signals through rapidly switching among the band group.

    摘要: In at least some embodiments, a communication system includes a receiver having a local oscillator (LO) for each of a plurality of frequency bands. Each LO is controlled by a separate phase-locked loop (PLL) that tracks carrier frequency offset (CFO) using a common phase error (CPE). The CPE is selectively weighted based on at least one inter-band frequency correlation (IFC) coefficient.

    摘要: The present invention provides a versatile system for optimizing pilot pattern diversity in a digital communications system—particularly in multiple antenna OFDM communications systems. According to the present invention, a receiving device within a communications system may receive transmissions from a first transmitting device (202) and a second transmitting device (204), on a single tone (214, 216) within a given time segment (206-212). The first transmitting device transmits a first pilot pattern to the receiving device on the tone. A differentiation scheme (200) is provided and utilized to transform a second pilot pattern from the second transmitting device, and the transformed second pilot pattern is transmitted to the receiving device on the tone.

    摘要: A wireless receiver for receiving an incoming signal having spatial and temporal diversity. The receiver uses noise-based prescaling of multiple receiver chain signals for optimally combining the receiver chain signals in a composite equalized signal and uses noise-based time-varying postscaling the equalized signal. The receiver determines noise-based scale factors by comparing signal symbols to dispersed replica symbols of a training sequence for the incoming signal.
