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.

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.

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.

摘要： In some embodiments of the present invention the nature of an input signal is identified and the amplification of a pre-amplifier and a power amplifier in a transmitter system are modified responsive to whether the momentary content of the input signal is a preamble or data and to the modulation rate of the input signal. In some other embodiments sets of amplification factors are set to reduce in-band noise at the antenna of the transmitter system.

摘要： A wireless network device may include a receiver having an active energy detection threshold and a processor to control the active energy detection threshold. The processor may determine preferred energy detection thresholds for the receiver for corresponding communication channels to which the receiver is tunable, and may select one of the preferred energy detection thresholds as an active energy detection threshold of the receiver for communication on a corresponding one of the communication channels. While the wireless network device is associated with another wireless network device of a wireless network over a communication channel, the processor may adjust the energy detection threshold of the receiver to changing conditions of the wireless network.
