20120257668 | TIME-VARYING LEAST-MEAN-FOURTH-BASED CHANNEL EQUALIZATION METHOD AND SYSTEM - The time-varying least-mean-fourth-based channel equalization method is an automated procedure that provides an adaptive equalizer in a CDMA receiver. Equalizer filter coefficients are estimated using a least-mean-fourth (LMF) error calculation based on a training set of symbols sent by the transmitter. When the LMF error calculation is combined with a power-of-two quantization (PTQ) process, superior receiver performance is achieved in a time-varying CDMA channel operating in non-Gaussian noise environments. | 10-11-2012 |

20150178547 | APPARATUS AND METHOD FOR IRIS IMAGE ANALYSIS - An apparatus including circuitry configured to receive a plurality of images and extract at least one iris image from each of the plurality of images. The circuitry is configured to receive a claimed identity iris image corresponding to an identity to be authenticated, normalize the iris images and the claimed identity iris image, and filter the normalized extracted iris images to select a subset of the normalized extracted iris images based on a similarity measurement relative to the normalized claimed identity iris image. The circuitry is configured to divide the normalized claimed identity iris image and each image of the subset of images into a plurality of sub-images, filter the sub-images to select the sub-image having a closest similarity measurement relative to a sub-image of the normalized claimed identity image in a corresponding sub-image position to the selected sub-image, and generate a composite iris image by fusing the selected sub-images. | 06-25-2015 |
