  • Systems and methods for positioning and messaging of reserved tones for peak-to-average ratio (PAR) reduction in DSL systems
    Patent number: 8885736
    Abstract: Systems and methods for reducing the peak-to-average ratio (PAR) at the transmitter can reduce the dynamic range required in various analog components. PAR can be reduced by applying a time-domain compensation signal which reduces the magnitude of peaks in the time-domain signal prior to transmission where the time-domain compensation signals use tones that are reserved for the purpose of reducing the PAR. The reservation of these reserved tones for PAR can be implemented by altering the typical startup procedures in a digital subscriber line (xDSL) system. The use of the reserved tones to reduce the PAR can be implemented using a low complexity algorithm or using an adaptive technique.

  • Flexibly transferring typed application data
    Patent number: 8296354
    Abstract: The present invention extends to using Simple Object Access Protocol (“SOAP”) to exchange typed objects, such as, for example, parameters for invoking methods. A computer system accesses typed object parameters corresponding to a typed object. The typed object is annotated with one or more message contract attributes of a message contract model defining a mapping between typed object parameters and corresponding SOAP elements. The computer system utilizes the message contract attributes to map the typed object parameters into a SOAP element and inserts the SOAP element into a SOAP envelope. A receiving computer system accessing the SOAP element and utilizes the message contract attributes to map the SOAP element back into the typed object parameters.

  • Systems and methods for transmit-only peak-to-average ratio reduction in the oversampled regime using reserved tones
    Patent number: 7974181
    Abstract: Systems and methods for reducing the peak-to-average power ratio (PAR) at the transmitter can reduce the dynamic range required in various analog components. PAR can be reduced by applying a time-domain compensation signal in the oversampled regime, using tones reserved for PAR reduction. A set of vectors corresponding to PAR tones is generated by processing out-of-phase symbols for each PAR tone to form a span matrix. The span matrix is used to find a best fit of a desired target signal to a time-domain compensation signal comprising only PAR tones.
