摘要： Electronic devices for communicating in wireless ad-hoc networks and multiple access systems (such as mobile radio telephone communications systems) are disclosed. For example, a disclosed transmitter can transmit data to a first receiver in an ad-hoc wireless network (or multiple access system) over a first channel and can, further, transmit data to a second receiver in the ad-hoc wireless network (or multiple access system) over a second channel that is separate from the first channel, where the first and second channels are determined by the respective receivers which will receive the first and second transmitted data. Accordingly, communications between transmitters and different receivers in the ad-hoc wireless network (or multiple access system) can be carried on simultaneously. Related receivers as well as methods, computer program products, and systems for communicating are also disclosed.

摘要： A method of controlling polling of slaves in a piconet includes polling the slaves in accordance with a weighted round robin (WRR) scheme and dynamically changing a weight of a participant-in-multiple-piconets (PMP) slave in order to compensate the PMP slave for absence of the PMP slave from the piconet.

摘要： The controllable oscillator in a phase-locked loop (PLL) can self-calibrate by tapping the PLL's feedback path with a suitable circuit or logic block. The logic block may include a counter. This enables the self -calibration/trimming to be handled completely within a product, such as a radio telephone, and no external instruments or software are needed for trimming.

摘要： A method of generating a quantized signal in a Sigma-Delta modulator (25) comprises the steps of feeding a modulator input signal to a quantizer (15) via at least one integrator (12, 13); generating in the quantizer (15) a quantized signal; feeding back the quantized signal to be subtracted from the modulator input signal; and generating a dither signal to be applied to a point in the Sigma-Delta modulator. The dither signal is applied to a selected one of a number of different points (11, 14) in the Sigma-Delta modulator (25) in dependence of a control signal. In this way a method of generating a quantized signal in a Sigma-Delta modulator is provided which provides optimal results for different modes of the application, such as phase modulation mode and frequency modulation mode in a Bluetooth receiver.

摘要： An output signal is generated for transmission in a telecommunications systems. This may involve generating an in-phase radio frequency signal by mixing an in-phase baseband signal with a first radio frequency mixer signal; and generating an alternative-phase radio frequency signal by mixing an alternative-phase baseband signal with a second radio frequency mixer signal. An output signal for transmission is generated by combining the in-phase radio frequency signal with the alternative-phase radio frequency signal, wherein the output signal has a frequency, fRF. The first and second radio frequency mixer signals are generated by generating a voltage controlled oscillator (VCO) output signal having a frequency, fVCO, such that fVCO = (n + ½) . fRF , wherein n = 1,2,3,...; and generating one or more fractional frequency divided signals from the VCO output signal, wherein each of the one or more fractional frequency divided signals has a frequency equal to fRF.
