20130253923 | MULTICHANNEL ENHANCEMENT SYSTEM FOR PRESERVING SPATIAL CUES - A method is disclosed for maintaining spatial queues in digital sound signals. Sound signals are received from each of a plurality of transducers. The sound signals are transformed using a common real-valued spectral gain, G, to maintain spatial cues within the sound signals, the common spectral gain, G, determined by: calculating G as a function of a derivative of a known cost function and as a function of at least one multichannel frequency-domain Bayesian short-time estimator. | 09-26-2013 |
20130249764 | COMPACT PLANAR INVERTED F-ANTENNA FOR MULTIBAND COMMUNICATION - A multi-band antenna for sending/receiving wireless communication signals in a plurality of frequency bands. The multi-band antenna has a feed element for sending/receiving signals associated with the wireless communication signals. A stepped-impedance structure is connected to the feed element. The stepped-impedance structure has a plurality of concatenated stepped-impedance elements with each stepped-impedance element having a predetermined impedance and a predetermined electrical length associated with a resonance mode for sending/receiving wireless communication signals in a respective frequency band of the plurality of frequency bands. | 09-26-2013 |
20130136857 | METHOD AND APPARATUS FOR RECOATING AN OPTICAL FIBER HAVING A NON-UNIFORM DIAMETER - An optical fiber recoating apparatus employs a variable size applicator for depositing a coating material in liquid form onto a portion of varying diameter optical fiber. The coating material is applied to the variable size applicator which is in continuous contact about the circumference of the optical fiber. At a constant speed the variable size applicator moves along the length of the optical fiber while simultaneously changing size to conform to the varying diameter of the optical fiber for applying a uniform coating thereto. | 05-30-2013 |
20080219371 | Channel estimation and ICI cancellation for OFDM - An iterative channel estimation and inter-carrier interference (ICI) cancellation process is provided for OFDM receivers, and more particularly for mobile OFDM receivers. The iterative process uses decision feedback to estimate both the channel gain and the ICI gains, the latter being the multiplicative gain applied to the adjacent sub-carriers. Thus the receiver performs equalization and ICI cancellation in an iterative fashion and is advantageous for estimating fast fading channels. | 09-11-2008 |
