20110021171 | SYSTEM AND METHOD FOR USE OF SIEVING IN GPS SIGNAL ACQUISITION - Systems and methods are disclosed herein to use sieving to reduce the number of hypotheses and the length of time for acquisition of GPS satellite signals. In sieving, hypothesis testing is performed after a short non-coherent integration duration on a first set of hypotheses. At the end of the non-coherent integration time, multiple candidate hypotheses having high likelihood of signal detection are identified. Further non-coherent integration of each candidate hypothesis is performed by using a tracking loop to remove Doppler frequency and code phase variations on the signal. In parallel, additional hypotheses testing is performed on a second set of hypotheses. At the end of the next non-coherent integration time, the best candidate hypotheses among the candidate hypotheses sieved from the first set of hypotheses running in the tracking loops and the candidate hypotheses from the second set of hypotheses are identified. This new set of candidate hypotheses replaces the previous candidate hypotheses and is tracked by the tracking loops. This process of short non-coherent integrations followed by track is repeated until a candidate hypothesis has a non-coherent integration that exceeds a detection threshold. | 01-27-2011 |

20110066857 | Method for secure delivery of digital content - Methods and apparatus for the secure and copy-proof distribution of digital content are disclosed. In a preferred embodiment of the invention cryptographic primitives (encryption algorithms, message-authentication codes, hash functions, random-number generators, etc.) are used in a novel security protocol. The invention may be utilized to protect a first-run movie that has been digitized in accordance with one of the current or forthcoming MPEG standards (e.g., MPEG-7). Content receivers or users first register their boxes. This registration information is stored in a secure database. When a subscriber registers, he then receives a box (interface to his player) that has been initialized to contain a number of tamper-proof secrets that are shared between the station and that particular box. The station stores an encrypted version of the digital content. This encrypted version ultimately arrives at some unprotected storage medium local to the player. Upon demand, the station delivers to the box the use-once computational ability to decrypt the content and display it on the player or terminal. | 03-17-2011 |
20120254272 | MULTI-STANDARD MULTI-RATE FILTER - A method is provided for decimating a digital signal by a factor of M and matching it to a desired channel bandwidth. The method applies the digital signal input samples to a (M−1) stage tapped delay line, downsamples the input samples and the output samples of each tapped delay line stage by a factor of M, and applies each of the M downsampled sample value streams to M allpass IIR filters, respectively. The M allpass IIR filtered sample streams are then summed and scaled by a factor of 1/M. The result can then be filtered by a digital channel filter. | 10-04-2012 |
