摘要:
A method for noise shaping includes: reducing a bit-depth of an input signal to obtain a quantized input signal; feeding a quantization error corresponding to the bit-depth reduction of the input signal into a feedback loop to the input signal, the feedback loop comprising a first quantization stage, a second quantization stage and a correction stage, both the first and second quantization stages operating at the bit-depth of the input signal and the correction stage operating at a bit-depth of the quantization error; and generating a noise-shaped output signal at lower clock rate than the input signal based on the feedback loop.

Some demonstrative embodiments include devices, systems and/or methods of controlling wireless communication based on an orientation-related attribute of a wireless communication device. For example, a wireless communication device may include a controller to receive from a sensor orientation-related information indicating an orientation-related attribute of the wireless communication device, and to control an antenna scheme of one or more antennas of the wireless communication device based on said orientation-related information.
摘要:
A method and device for adaptive control of transmission parameters such as data rate, fragmentation and request to send protection. Packet error rates for frames transmitted with and without request to send protection are computed and compared to determine whether error rates are attributable to noise or to collision. If error rates are attributable to noise, data rates may be adjusted and fragmentation may be activated. If error rates are attributable to collisions, request to send protection may be activated or adjusted.

Briefly, some embodiments of the invention provide devices, systems and methods of crosstalk cancellation. For example, an apparatus may include a first transmission path to carry a first signal with information to be transmitted; a second transmission path to carry a second signal with information to be transmitted; a scaler associated with said first transmission path to scale said first signal into a scaled first signal; and a combiner to combine said scaled first signal and said second signal into a combined second signal on said second transmission path.

摘要:
Briefly, a method and apparatus to compensate an imbalance of a modulator by providing calibration parameters to a calibration network. The modulator may receive a pair of predetermined sinusoidal in-phase and quadrature signals and output a distorted modulated signal. A processor may process spectral parameters at first and second harmonics of a detected envelope signal of the distorted modulated signal may generate the calibration parameters.
