20110197062 | METHOD AND SYSTEM FOR LICENSE MANAGEMENT - Embodiments of the invention relate to methods, apparatus and systems, including computer program products for license management in one or more computer systems. A first computer runs a master license server process instance. The master license service process instance is associated with a hardware identifier relates to the first computer and has a license to run a predefined number of concurrent production license server process instances that are responsible for license management towards clients. A request is received by the master license server process instance for a license from a production license server process instance in a second computer. The master license server process instance provides a virtual identifier to the production license server process instance to be used as a unique identifier for license management purposes towards clients by the production license server process instance. The virtual identifier is cryptographically secured against modification. | 08-11-2011 |

20090080506 | RECEIVER EMPLOYING NON-PILOT REFERENCE CHANNELS FOR EQUALIZING A RECEIVED SIGNAL - In one embodiment, a receiver has a reference generator and a main equalizer. The reference generator equalizes a received signal using one or more pilot reference signals. Then, the reference generator decodes one or more predetermined data channels of the equalized signal, makes hard decisions on the data of each decoded channel, and regenerates the original coding sequence of each decoded channel. The main equalizer uses each re-encoded channel as an additional reference signal along with one or more pilot signals to equalize a time-delayed version of the received signal. In alternative embodiments, the receiver might also have a step-size generator which selects optimum step sizes from a look-up table based on the number of re-encoded channels and the power of those channels. The step size is then used by the main equalizer along with the re-encoded channels to equalize the time-delayed received signal. | 03-26-2009 |
20090296798 | HSDPA CO-PROCESSOR FOR MOBILE TERMINALS - In one embodiment, an HSDPA co-processor for 3GPP Release 6 Category 8 (7.2 Mb/s) HSDPA that provides all chip-rate, symbol-rate, physical-channel, and transport-channel processing for HSDPA in 90 nm CMOS. The co-processor design is scalable to all HSDPA data rates up to 14 Mb/s. The coprocessor implements an Advanced Receiver based on an NLMS equalizer, supports RX diversity and TX diversity, and provides up to 6.4 dB better performance than a typical single-antenna rake receiver. Thus, 3GPP R6 HSDPA functionality can be added to a legacy R99 modem using an HSDPA co-processor consistent with embodiments of the present invention, at a reasonable incremental cost and power. | 12-03-2009 |

20090092181 | SCALING EQUALIZER COEFFICIENTS AFTER AUTOMATIC GAIN CONTROLLER GAIN ADJUSTMENTS - In one embodiment, a receiver comprises an automatic gain controller (AGC), an equalizer, a controller, and a register interface. The AGC makes gain adjustments to compensate for changes in the average amplitude of a received signal. The equalizer has a coefficient updater that calculates coefficients and a finite impulse response (FIR) filter that applies the coefficients to the received signal to generate an equalized signal. During gain adjustments by the AGC, the register interface provides a weight freeze signal to the coefficient updater, which subsequently freezes the updating of the coefficients for a freeze duration period. Then, register interface provides a scaling factor, generated by the controller based on the size of the gain adjustment, to the coefficient updater. At the end of the freeze period, coefficient updater applies the scaling factor to the coefficients and unfreezes the coefficient updating. | 04-09-2009 |
