  • Patent number: 8279846
    Abstract: A broadcast control channel (BCH) transport block is communicated in a cellular communications system having a physical layer in which information is communicated in one or more frames, wherein the BCH transport block represents BCH information. This involves coding (901) the BCH transport block (1001, 1101) to generate M bits of coded information. Nframes segments of coded bits are formed (903) from the M bits of coded information, wherein the BCH information can be derived from any one of the Nframes segments of coded bits. A unique one of Nframes mapping functions is applied (905) to each of the Nframes segments of coded bits to produce Nframes mapped segments of coded bits. A different one of the Nframes mapped segments of coded bits is transmitted (907) in each of Nframes frames. This enables multi-frame timing to be determined even when fewer than all BCH segments are received.

  • Patent number: 8279743
    Abstract: In an OFDM communications system receiver, channel estimates are processed to remove or reduce noise, exploiting the orthogonality of pilot patterns. The de-noised channel estimates are then used to compute inter-cell interference. The noise effects of orthogonal pilot patterns are selectively removed from channel samples in estimating inter-cell interference, depending on whether data subcarriers are subject to the same interference as pilot subcarriers, and whether data subcarriers are subject to interference from sectors with pilot patterns orthogonal to those in the transmitting sector. A further calculation removes noise from cells not identified by an orthogonal pilot sequence, which may be particularly applicable when large variations exist in the frequency domain of the propagation channel across a pilot pattern.

  • Patent number: 8275074
    Abstract: A received OFDM signal is processed to determine a plurality of reference delays, which may include the path delays of a multipath channel. The effective channel estimates corresponding to each reference delay are determined, as is the covariance of the ISI and noise components observed at each delay. Combining weights resulting in maximum post-combining SINR are determined for all subcarriers. A corresponding plurality of FFTs is applied to the incoming sample stream, one at each of the reference delays. The individual subcarriers from each FFT output are then combined using the combining weights. This produces a single FFT output with suppressed ISI, which is used in further processing.

  • Patent number: 8275023
    Abstract: Signal impairment correlations for multiple signals in a received multipath signal are constructed by fitting parametric models associated with each high-data-rate signal in the multipath against measured impairment correlations. The estimated model fitting parameters are applied to form impairment correlation estimates for all signals. The models comprise a separate impairment covariance matrix scaled by a model fitting parameter for each high-data-rate signal and a noise covariance matrix scaled by a noise element model fitting parameter. The model fitting parameters may be estimated by a least-squares formulation and applied to form impairment correlation estimates for all signals of interest. The resulting impairment correlation estimates may be provided to G-RAKE receivers or joint scaling demodulators to demodulate the signals while suppressing interference from the high-data-rate signals.

  • Patent number: 8269522
    Abstract: A current boost circuit acts as an “eye opener” for a digital bus line. A controlled current injects a fraction of the normal signaling current magnitude from a source driver onto the bus line, after a transition between the two logical states on the bus line is detected. The duration of the additional current injection is a fraction of the unit interval. In one embodiment, a linear system uses the summation of a proportional boost current and a delayed and negated proportional boost current. In another embodiment, a positive or negative edge detection circuit triggers a monostable pulse generator that controls the injection of short bursts of additional current into the bus lines. In some embodiments the boost current is suppressed when the bus line is driven from a driver other than the source driver.

  • Patent number: 8272065
    Abstract: A web browser client includes an aggregated web application runtime environment that controls access by a program fragment of an aggregated web application to a resource therein based upon the originating domain of the program fragment. To do so, the aggregated web application runtime environment appends an access attribute to the Document Object Model (DOM) node associated with the resource. This access attribute is associated with a plurality of access rights definitions where each access rights definition defines a set of access rights to the resource for program fragments originating from a domain with a specific access rights status. Accordingly, the aggregated web application runtime environment sets one or more access rights statuses of the originating domain of the program fragment, and thereafter, grants or denies the program fragment access to the resource based upon one or more sets of access rights defined for that program fragment.

  • Patent number: 8270436
    Abstract: Synchronization between a transmitter and a receiver with respect to the boundary of higher-layer logical data structures is improved by considering both the statistical likelihood of the value of a transmitted boundary indicator and the quality of the channel during the transmission. A boundary indicator received under poor channel quality, that is decoded to a statistically unlikely value, is suspect and one or more retransmission is requested. A reliable value of the boundary indicator is a retransmitted boundary indicator received during good channel conditions; the value of two boundary indicators received successively, both under poor channel conditions, that decode to the same value; or a majority vote of three successive boundary indicators, the first two received under poor channel conditions. The accuracy of the received boundary indicator is increased, at a cost of one, or at most, two, retransmissions.

  • Patent number: 8268173
    Abstract: A method of biologically treating wastewater with an integrated fixed film activated sludge process. The integrated fixed film activated sludge process includes biomass suspended in mixed liquor and biomass disposed on carriers. Under certain conditions the dissolved oxygen concentration in a reactor that includes the mixed liquor, biomass suspended in the mixed liquor, and the biomass on the carriers, biological treatment is performed primarily by the biomass in the mixed liquor. This is achieved by controlling or maintaining the dissolved oxygen concentration in the reactor at a relatively low concentration. When the biomass suspended in the mixed liquor is unable to adequately biologically treat the mixed liquor, the dissolved oxygen concentration in the reactor is controlled or maintained at a relatively high concentration. This enables biomass on the carriers to contribute more to the biological treatment of the mixed liquor than when the dissolved oxygen concentration was maintained relatively low.

  • Patent number: 8265213
    Abstract: In wireless communication networks, potentially significant interference arises at a given targeted receiver because of unrelated transmissions from a neighboring, interfering transmitter. According to apparatuses and methods described and claimed herein, a first transmitter provides for cancellation of partially known interference at a targeted receiver by employing a transmit diversity based interference cancellation method, wherein it transmits diversity combinations of desired and interfering symbols. Correspondingly, the targeted receiver employs diversity combining of the received signals to cancel interference attributable to the interfering symbols.
