摘要： In described embodiments, elements of a wireless home network employ learned power security for the network. An access point, router, or other wireless base station emits and receives signals having corresponding signal strengths. Wireless devices coupled to the base station through a radio link are moved through the home network at boundary points of the home and the signal strength is measured at each device and communicated to the base station. Based on the signal strength information from the emitted signals measured at the boundary points and/or from measured signal strength information of signals received from the boundary points, the base station determines a network secure area. The base station declines permission of devices attempting to use or join the home network that exhibit signal strength characteristics less than boundary values for the network secure area.

摘要： For a digital communications receiver, a clock and data signal recovery circuit and method use an all digital delay locked loop timed by an on-chip transmit clock signal. The digital delay locked loop includes a phase detector and loop filter. The phase detector determines, for each data signal rising or falling edge, if the current delay of a reference clock signal leads or lags the data signal edge. The loop filter examines the stream of such lead/lag indications, performs a nonlinear filtering process thereon, and in response increases or decreases the clock signal phase appropriately.

摘要： An equalizer receives an analog input signal and filters the signal to undistort the input signal. A converter stage converts the analog input signal into a digital output signal for use in a digital system. A bit sequence indicator analyzes the structure of the digital output signal to determine whether any errors have occurred in transmission and conversion. An adaptor state machine causes the modification of the analog signal based on a feedback loop including information on the errors detected in the packets of digital signals, rather than the analog data itself.

摘要： Frequency spectrum spreading of a timing recovery circuit, such as a PLL, is controlled by periodically calculating each value for a divisor, M, of a fractional divider in the feedback path of the PLL. The fractional divider divides the output signal of a voltage-controlled oscillator (VCO) of the PLL by the divisor, M, and the value for divisor, M, is periodically updated based on a spreading profile. The output of the fractional divider and a reference clock signal are provided to a phase detector of the PLL so as to cause the PLL to slew the output frequency of the PLL in accordance with the spreading profile.
