| 20080283780 | DEVICE HAVING GALVANIC OPTOCOUPLING - The present disclosure relates to an architecture of a device with galvanic optocoupling of the type having at least one optical source and one optical detector, optically connected by means of an insulation layer that functions to transmission optical signals, and having at least one input terminal and one output terminal, the optical source and the optical detector connected to a respective first and second voltage reference. The optical source is realized by a structure integrated directly above the insulation layer in correspondence with the optical detector, the architecture thus completely realized inside a single integration island. | 11-20-2008 |

| 20080318530 | Sir Estimation Techniques - The estimated power levels that are used to estimate a signal-to-interference ratio (SIR) are filtered so as to minimize the mean-square error (MSE) of the estimated power estimates. First order infinite impulse response (IIR) filters are used to filter both the signal power estimates and the noise power estimates. Optionally, estimates of the average signal power and average interference power are filtered using Weiner linear prediction filters. The SIR estimates are suitable for use in a transmission channel that includes fading as well as interference, and are suitable for use in BPSK, QPSK, and other modulation systems. | 12-25-2008 |
| 20090180522 | FIRST SIGNIFICANT PATH DETECTION - A scheme determines the first significant path (FSP) of a received multipath signal, from data defining the relative delay and the amplitude of the individual signal paths occurring in a series of time frames. The scheme includes filtering the data to spread the signal paths, performing a persistence test between frames to reject spurious signal paths, combining the energy of the signal paths in a frame, applying a test to determine the time at which the combined energy satisfies a criterion, and selecting the FSP dependent on that time. The combined energy may be evaluated within a sliding window, and the position of the window within the frame determined that maximizes the combined energy. Alternatively, the combined energy may be evaluated as the cumulative energy through the frame, and the position determined at which the cumulative energy reaches a threshold. | 07-16-2009 |
| 20100070826 | TURBO DECODER WITH EXTRINSIC INFORMATION SCALING MODULES - The invention related to a turbo decoder comprising SISO decoding modules each other interconnected in a feedback control scheme having scaling modules for applying a scaling factor to extrinsic information delivered by said SISO decoding modules. The turbo decoder comprises a selection module for adaptively selecting said scaling factor based on a number of decoding iterations of the turbo decoder. | 03-18-2010 |

| 20090323874 | CHANNEL ESTIMATION USING COMMON AND DEDICATED PILOTS - The present invention relates to a receiver apparatus and method of channel estimation in a telecommunication system which provides at least two pilot sequences, and to a computer program product. Channel estimation is achieved by estimating channel taps separately for each of the at least two pilot sequences in every transmission block, and for applying estimated channel taps obtained from the estimation to at least one of a temporal and spatial filtering or combining operation to refine the channel estimate. Accordingly, temporal correlations and cross-correlations of the at least two pilot sequences are exploited without requiring knowledge of path delays and beamforming parameters. | 12-31-2009 |

| 20110144404 | MTO Feed Purification - A process is presented for improving the quality of an oxygenate feedstream to an oxygenate to olefins conversion reactor. The process includes passing the feedstream to a fractionation column having a sufficient number of trays to remove the sodium in the form of sodium hydroxide. The fractionation column is also sized to have a sufficient number of trays to minimize the amount of oxygenates being passed out with the removed sodium hydroxide. | 06-16-2011 |
