  • Patent number: 8718645
    Abstract: In one embodiment, the present invention includes a method for determining if a mobile station is to be resynchronized on a handover from a first serving cell to a second serving cell. If so, a first downlink hardware storage may be drained to a predetermined level. This level may then be maintained during the resynchronization.

  • Patent number: 8452641
    Abstract: Systems, methods, and computer-readable storage media are described for estimating real estate property values based on an adjusted repeat sales model using a regularized estimator. In one exemplary embodiment, a computer-implemented method calculates data for estimating the adjustments from an aggregated level to a first disaggregated level by marking a first transaction to a second transaction using a repeat sales house price index function at the aggregated level. The method also determines, using the calculated data, a regularized estimate of the deviation between the repeat sales house price index at the aggregated level and a repeat sales house price index at the first disaggregated level. The method further calculates the repeat sales house price index at the first disaggregated level based on the determined regularized estimate of the deviation from the aggregated level.

  • Publication number: 20110174457
    Abstract: A process for optimizing steel fabrication. The process includes optimization of treatment in the ladle based on accurate determination of steel weight, slag carryover and furnace heel. The unification of the dip test process together with ladle profiling using information from the slag, side and bottom regions of the ladle results in the quantitative determination of key factors to optimize steel composition with minimum slag carryover in the absence of scales to determine required masses of metal charge and ladle weight as examples. Caprices of the process include significant improvements in ladle refractory and specification steel quality.

  • Patent number: 7890072
    Abstract: A wireless communication apparatus includes a mechanism for estimating carrier-to-interference (C/I) ratio using a variable bandwidth filter. More particularly, the wireless communication apparatus includes a channel equalization unit coupled to a C/I ratio estimation unit. The channel equalization unit may be configured to calculate instantaneous carrier-to-interference (C/I) ratio values of a received signal. In addition, the C/I ratio estimation unit may be configured to calculate a C/I ratio estimate by filtering successive ones of the instantaneous C/I ratio values. The C/I ratio estimation unit may also be configured to determine whether a transmitter of the signal is transmitting voice data in a voice channel of the signal. The C/I ratio estimation unit may be further configured to inhibit the filtering in response to determining the transmitter of the signal is not transmitting the voice data such as during DTX mode, for example.

  • Publication number: 20100241422
    Abstract: In one embodiment, the present invention includes a method for maintaining a vocoder and channel codec in substantial synchronization. The method may include receiving a configuration message that includes rate information and an effective radio block identifier at a mobile station, coding a current radio block via a vocoder and channel codec, configuring an encoding portion of the vocoder and channel codec with the rate information after performing the coding, and then coding the effective radio block using the rate information. Other embodiments are described and claimed.

  • Patent number: 7801207
    Abstract: A communication apparatus includes a radio frequency (RF) circuit configured to operate on an RF signal, and a digital processing circuit that is coupled to the RF circuit. The digital processing circuit may operate in association with the RF circuit according to a time domain isolation technique. In addition, the digital processing circuit includes a scheduler that may schedule a channel equalization task for each of one or more respective receive time slots. The scheduler may also schedule a decode task to obtain slot allocation information for each of the one or more respective receive time slots.

  • Patent number: 7433393
    Abstract: A method of operating a radio-frequency (RF) circuitry and a signal-processing circuitry in a mobile telephone apparatus includes at least partially disabling the signal-processing circuitry while transmitting or receiving signals. In one example, a processor is efficiently disabled by generating and servicing an interrupt of relatively high priority. One advantage of this example is that preexisting, legacy code can be maintained, while still achieving the desired objectives. The processor can be enabled by generating and servicing a second high priority interrupt.

  • Patent number: 7414560
    Abstract: A wireless communication device reduces undesired audio underflow in a digital to analog receive path that employs time domain isolation. One or more buffers in the receive path receive processed audio samples from a signal processor. A control circuit senses when the buffers in the receive path are substantially empty. In response to a substantially empty determination by the control circuit, the control circuit instructs one of the buffers to repeat the last processed audio sample which that buffer received to reduce or avoid audio underflow.
