    摘要： An RFIC includes an RF section, a memory interface, a display interface, an audio codec, a bus matrix, and a processing unit. The RF section converts a first inbound RF signal into a first inbound symbol stream and converts a second inbound RF signal into a second inbound symbol stream. The memory interface is operably coupled to retrieve a video file from memory and the display interface is operable to provide video data to a display. The audio codec converts an output digital signal into an output voice signal. The processing unit converts the first inbound symbol stream into streaming video data; converts the second inbound symbol stream into the output digital signal; and facilitates providing, via the bus matrix, at least one of: the video file to the display interface as the video data; the streaming video data to the display interface as the video data; and the digital output signal to the audio codec.

    摘要： A receiver architecture for canceling blocking signals in the receive path includes a low noise amplifier for receiving and amplifying an inbound RF signal to produce an amplified inbound signal, in which the inbound RF signal includes a modulated RF signal and a blocking signal, and a cancellation module for substantially canceling the blocking signal from the amplified inbound RF signal and substantially passing the modulated RF signal. The cancellation module cancels the blocking signal by generating an injection signal representative of the blocking signal, combining the blocking signal with the injection signal to produce an error signal, updating the injection signal based on the error signal and using the injection signal to cancel the blocking signal from the amplified inbound RF signal.

    摘要： An integrated circuit (IC) includes an RF section, a DSP, and a plurality of processors. The RF section and the DSP process an inbound RF signal to produce inbound data and process outbound data to produce an outbound RF signal. In addition, the DSP converts an outbound analog audio signal into an outbound digital audio signal and converts an inbound digital audio signal into an inbound analog audio signal. A first processor converts the inbound data into the inbound digital audio signal and converts the outbound digital audio signal into the outbound data. A second processor performs a user application that includes at least one of generation of the inbound analog audio signal and generation of the outbound analog audio signal and performs an operating system algorithm to coordinate operation of the user application.
