20130230094 | MULTI-ANTENNA RECEIVER IN A RADIO CONTROLLED CLOCK - A novel and useful multi-antenna receiver that receives, demodulates and decodes a broadcast signal, whose modulation and encoding of time and timing information allow for reliable and power-efficient operation. The multi-antenna receiver of the present invention is adapted to eliminate or substantially reduce the reception nulls that occur in receivers having a single antenna that is placed in a fixed position. Two or more antennas are employed whereby the receiver generates a combined signal based on a combination of the individual antenna signals or selects one of the antenna signals for input to the receiver based on desired criteria such as signal-to-noise-and-interference-ratio (SNIR). This results in greater robustness of the communication link by reducing or eliminating reception nulls and by rejecting interference through the selection of the antenna for which the signal-to-interference ratio is higher. The invention includes various antenna configurations that are adapted to reuse a single core for multiple antennas or to otherwise reduce size and/or cost. | 09-05-2013 |
20140050315 | HIGH-SPEED IN-MEMORY QR DECOMPOSITION USING FAST PLANE ROTATIONS - A system and method for processing an input matrix and a MIMO receiver employing the system or the method.
