    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.

    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: To detect a special burst sequence, a cross correlation (C) is compared to a square root of an estimated noise variance (σ) in conjunction with a threshold value (Th). In one aspect of the disclosure, the threshold value may include multiple threshold values. The multiple threshold values may be compared to an intensity or level of a special burst metric (C/σ) to facilitate determination of the special burst sequence. For example, when a special burst metric C/σ is greater than a second threshold value (Th2) it may be determined that a special burst sequence exists. However, when the special burst metric C/σ is greater than a first threshold value (Th1), but less than the second threshold metric (Th2), it may be determined that detection of a special burst is unclear. In this case, a TFCI value may be used to confirm whether a special burst is detected.

    摘要: In certain communication systems, such as TD-HSDPA communications, channel quality index (CQI) reporting is based on a predetermined configuration, such as a mobile device (UE) reporting a CQI for a most recently received data transmission. This configuration may lead to errors if a UE reports a CQI for a certain data transmission but the base station (node B) believes the CQI corresponds to a different data transmission, such as a later transmission the UE never received due to an error processing control channel information. Offered is an indicator to accompany CQI reports. The indicator indicates to the node B which communication resource corresponds to the CQI report.
