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： Method and apparatus for OFDM synchronization and channel estimation. In a temporal embodiment, received embedded system pilot symbols are inverse Fourier transformed at expected index locations and correlated with computed complex conjugates of inverse Fourier transforms of pilot symbols for providing a correlation function for the channel impulse response. In a frequency domain embodiment, embedded system pilot symbols are augmented with pilot-spaced inferred guard band symbols, multiplied by scaled complex conjugates of computed pilot systems, and inverse Fourier transformed into the channel impulse response. Time and frequency are synchronized in feedback loops from information in the channel impulse response. The channel impulse response is filtered, interpolated, and then Fourier transformed for determining channel estimates for equalization.

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.

摘要： Techniques for classifying RF channels in a first system (e.g., a Bluetooth system) to mitigate the deleterious effects of interference from a second system (e.g., a WLAN system) are described. One or more metrics (e.g., PER and/or RSSI) are determined for the RF channels. Each RF channel may be classified as good or bad based on the metric(s) for that RF channel. Whether excessive interference is observed on any frequency channel for the second system is determined based on the metric(s) for the RF channels. Excessive interference may be declared if the average PER for RF channels overlapping a frequency channel exceeds a threshold THW or if the number of bad RF channels within the frequency channel exceeds a threshold THC. A set of usable RF channels is formed and includes good RF channels not overlapping any frequency channel with excessive interference.

或者频率信道内的不良RF信道的数量超过阈值TH < SUB>。 形成一组可用的RF信道，并且包括不会与具有过多干扰的任何频道重叠的良好RF信道。
