20120106530 | Multicarrier Radio Receiver and Method for Receiving Multiple Carriers - A radio receiver receives multiple radio frequency (RF) carriers where each RF carrier corresponds to a logical entity or object used in multi-carrier communications called a cell. A receiving radio node receives signals on serving cells, including a serving cell on a primary carrier and a serving cell on a secondary carrier, and on neighboring cells, including a neighboring cell on the primary carrier and a neighboring cell on the secondary carrier. Initially, a power delay profile is calculated for each of the serving cells and the neighboring cells. An association is determined between at least one cell on the primary carrier and at least one cell on the secondary carrier based on the calculated power delay profiles. The association is then later used in performing interference cancellation in the radio node. | 05-03-2012 |

20090312056 | Relative Frequency Error Compensation for Multi-Carrier Receivers - A wireless receiver utilizes a single analog oscillator to down-convert multi-carrier signals in one or more receiver front-end paths. The received signals are digitized, and the different carrier signals received at each antenna are separated in digital domain by mixing the digitized signal from each antenna with a carrier/antenna separation digital oscillator to down-convert a desired carrier signal and low-pass filtering to remove unwanted carriers. A coarse frequency correction adjusts the analog oscillator, and fine frequency corrections adjust digital oscillators mixing with the separated signals. In one embodiment, the fine frequency correction is applied to the carrier/antenna separation digital oscillators in the separation function.

20130314429 | ADAPTIVE FRAME BUFFER COMPRESSION - Image data is subject to compression and decompression when it is respectively written to and read from a frame buffer. If a portion of the image data is identified as static (subject to less than a threshold amount of change for greater than a threshold time), then compression control parameters used for compression of that portion of the image are adjusted so as to increase the compression ratio achieved, hold the degree of lossiness substantially constant and increase the energy consumed while compressing that portion. The increased energy consumption during this high compression ratio compression is likely compensated for by a reduction in energy subsequently consumed when writing that frame-buffer image data to the frame buffer and reading that frame-buffer image data multiple times from the frame buffer. The compression characteristics varied may be to increase the block size used in the compression. Other variations in compression applied may be to change from single-pass compression to multi-pass compression, switch compression on and off altogether, or reorder the data when it has been compressed so as to match the order it will be read and so achieve support for longer read burst. | 11-28-2013 |
