Abstract: A read reference circuit for a sense amplifier within a chalcogenide memory device is disclosed. The read reference circuit provides a reference voltage level to the sense amplifier for distinguishing between a logical “0” state and a logical “1” state within a chalcogenide memory cell. In conjunction with a precharge circuit, the read reference circuit generates a selectable read reference current to the sense amplifier in order to detect the logical state of the chalcogenide memory cell. The precharge circuit precharges the bitlines of the chalcogenide memory cell before the sense amplifier detects the logical state of the chalcogenide memory cell.

Abstract: Data estimation is performed in a wireless communication system using both oversampling and multiple reception antennas. A receive vector is produced for each antenna at a sampling interval which is a multiple of the chip rate of the received signal. A channel response matrix is produced for each antenna at a preferred multiple of the sampling rate. Each receive vector is processed using a sliding window based approach, where a plurality of successive windows are processed. For each window, a combined circulant channel response matrix is produced using the channel response matrices. Using the combined circulant channel response matrix and a combined received vector comprising each received vector in a discrete Fourier transform based approach to estimate a data vector corresponding to that window; and combining the data vector estimated in each window to form a combined data vector.

Abstract: A receiver or an integrated circuit (IC) incorporated therein includes a fast Fourier transform (FFT)-based (or hybrid FFT-based) sliding window block level equalizer (BLE) for generating equalized samples. The BLE includes a noise power estimator, first and second channel estimators, an FFT-based chip level equalizer (CLEQ) and a channel monitor unit. The noise power estimator generates a noise power estimate based on two diverse sample data streams. The channel estimators generate respective channel estimates based on the sample data streams. The channel monitor unit generates a first channel monitor signal including truncated channel estimate vectors based on the channel estimates, and a second channel monitor signal which indicates an approximate rate of change of the truncated channel estimate vectors. The FFT-based CLEQ generates the equalized samples based on the noise power estimate, one-block samples of the first and second sample data streams, the channel estimates and the monitor signals.

Abstract: In a method and device for correcting distortion in MRI, k-space data are acquired in a number of data readout directions, the data are converted into a number of images, and a corresponding pixel shift map is generated for each image. The geometric distortion in the corresponding image is corrected according to the pixel shift map, and then all geometric distortion-corrected images are combined. Since movement distortion normally exists in the data readout direction, collecting the k-space data from a number of data readout directions can effectively correct movement distortion. Moreover, correcting the geometric distortion for the images converted from data acquired in a number of data readout directions according to the pixel shift map can reduce the geometric distortion of the final image generated from combination of images. The method and device correct not only movement distortion of MRI images, but also geometric distortion of MRI images.
