    Abstract: A peak to average power ratio signal is generated from a first mapping function that selects the peak to average power ratio signal that corresponds to the data rate or data format of the signal to be transmitted. The selected peak to average power ratio signal is summed with a desired average transmit power signal. The resulting summation signal is input to a second effectively continuously valued mapping function comprising a table that has a plurality of power amplifier control signal values each with a corresponding peak transmit power. Each peak transmit power signal value results in a power amplifier control signal value that achieves the best possible transmitter power efficiency while still meeting out of band spurious emissions and waveform quality requirements. The summation signal value maps to one of the power amplifier control signal value that is then used to adjust a parameter such as bias of the power amplifier.

    Abstract: The present invention provides a method of printing which includes providing a substrate having an inked surface. The inked surface is typically achieved using an offset lithographic printing press. A thermoplastic polymer powder is applied to the inked surface. The surface is then fused. An advantage of the prepared substrate is that there is reduced contamination of electrostatographic fusing systems when fused by heat and pressure fixing. Another aspect of the invention further provides a method of fusing a substrate having an inked surface wherein a thermoplastic powder has been applied to the inked surface prior to stacking the uncured offset prints.

    Abstract: In one illustrative example of the present application, a mobile communication device has one or more processors, a wireless transceiver adapted to provide communications through a wireless communication network, and a buffer memory for use in buffering a Push-To-Talk (PTT) communication from the mobile communication device. The one or more processors are operative to produce a mobile device indication message which indicates the mobile device's support for buffering of the PTT communication. This message is transmitted by the wireless transceiver to a PTT service entity through the wireless network. The one or more processors may be further operative to receive, from the PTT service entity through the wireless network, a network indication message which instructs the mobile device whether to use buffering for the PTT communication. The mobile device may use the buffer memory for the buffering of the PTT communication based on the network indication message from the PTT service entity.
