Abstract: A testing system tests a device under test (DUT) by emulating at least one radio access protocol. The testing system includes at least one transmitter, multiple receivers, multiple radio frequency (RF) heads, multiple horns, and multiple combiners. The transmitter(s) are configured to use an intermediate frequency for transmission. The receiver(s) are configured to use an intermediate frequency for reception. The RF heads up-convert the intermediate frequency from the transmitter(s) to RF used by the DUT and down-convert the RF used by the DUT to the intermediate frequency used by the receiver(s). The combiners each correspond to a different receiver and combine beamformed signals received from the DUT via two different RF heads and via the horns. The horns transmit RF signals to the DUT and receive RF signals from the DUT using two different polarizations.

Abstract: There is provided a method of implementing carrier aggregation on a first transceiver. The method comprises receiving and decoding, during a first subframe, channel quality information from user equipment and transferring, before the expiry of a second subframe immediately following the first subframe, the decoded channel quality information over a direct physical link to a second transceiver, for use in decoding further channel quality information from the user equipment.

Abstract: The disclosed embodiments provide a system that facilitates driving a display in a computer system. During operation, the system receives an input video stream from a graphics source, wherein the input video stream comprises a sequence of video frames. Next, the system directs the input video stream through a set of two or more memory buffers including a front buffer and a back buffer to produce an output video stream, which is used to drive the display. While directing the input video stream through the set of memory buffers, the system writes a video frame from the input video stream into the back buffer, and concurrently drives the output video stream from a preceding video frame in the front buffer. When the writing of the video frame completes, the system switches buffers so that the back buffer becomes the front buffer, which drives the output video stream, and the front buffer becomes either a spare buffer or the back buffer, which receives a subsequent frame from the input video stream.

Abstract: A radio transceiver apparatus configured to transmit and receive radio frequency signals, the apparatus comprising, a sample clock configured to generate samples at a clock frequency fs, a processor configured to generate a transmission data stream signal, wherein the transmission data stream signal comprises frames separated by frame boundaries between the frames, and wherein the frames are comprised of at least one sample, and a sample clock correction unit, wherein in a first transmission configuration when the clock frequency fs is greater than a desired clock frequency fr, the sample clock correction unit is configured to insert at least one sample into at least one frame boundary between frames, or in a second transmission configuration when the clock frequency fs is less than a desired clock frequency fr, the sample clock correction unit is configured to remove at least one sample from at least one frame boundary between the frames.

Abstract: A transceiver adapted to emulate devices using one or more of a plurality of different radio access protocols. The transceiver comprises a timing module, the timing module being adapted to maintain a record of the current timing state which would apply to each of the different radio access protocols the transceiver is able to use, if that radio access protocol was being used. When the transceiver changes a radio access protocol being used to emulate a device from a first radio access protocol used to emulate a first device to a second radio access protocol used to emulate a second device, the transceiver is adapted to use the record of the current timing state which would apply to the second radio access protocol to set the timing of the second radio access protocol.
