    摘要: Provided is automatic gain control (AGC) in which a feedback filter has a parameter that is changed based on information regarding data-packet boundaries. In one representative embodiment, the bandwidth of the filter temporarily is increased, or the time constant of the AGC filter temporarily is decreased, within a vicinity of each actual or potential packet boundary.

    摘要: Provided are systems, methods and techniques for predicting a communication channel parameter. In one representative embodiment, values of a communication channel parameter are estimated at a plurality of previous points in time, values are predicted for the communication channel parameter at a plurality of such previous points in time, using a plurality of the channel estimates, and then the channel estimates are updated using the predictions, with the latter prediction and estimation steps being repeated until a specified condition has been satisfied.

    摘要: A method and system is disclosed for providing an automatic gain control in signal processing. After receiving a stream of analog signals, a gain is adjusted on the received analog signals using a first set of gain compensation parameters. Then, the adjusted analog signals are converted to digital signals. A predetermined number of digital signals are collected from the converted digital signals within a predetermined time period. The collected digital signals are delayed from being transferred out for further demodulation processing for a predetermined delay time. At the same time, a second set of gain compensation parameters are estimated based on the collected digital signals. The estimated second set of gain compensation parameters are applied to the delayed digital signals.

    摘要: Provided are digital processing apparatuses and techniques for estimating the fractional exponentiation of the base number 2, i.e., 2f where f is a fractional value. In one representative embodiment, a calculation is made of a folded quantity, which is equal to 1−f if f is greater than a specified threshold and is equal to f otherwise; then, a function of the folded quantity is calculated; and finally, the function of the folded quantity is subtracted from the fraction f and 1 is added. In another embodiment, 2f is approximated by calculating 1+f′ in the binary numbering system.
