摘要： In one method, an uplink signal carrying at least one block of transmitted samples is transmitted, and a distorted copy of the uplink signal is received as a downlink signal. A plurality of blocks of received samples are generated based on the received downlink signal, and a time delay and frequency offset between the uplink and downlink signals are determined based on a correlation between the block of transmitted samples and at least one of the plurality of blocks of received samples.

摘要： A method for modulating first and second bit streams in a communications network that supports at least one of a binary phase-shift keying (BPSK), a quadrature phase-shift keying (QPSK) or a quadrature amplitude modulation (QAM) constellation uses hierarchical modulation. A hierarchical modulation parameter that varies within the network is set. The first bit stream is modulated based on a first constellation of the hierarchical modulation and the hierarchical modulation parameter. The second bit stream is modulated based on a second constellation in the first constellation.

摘要： The present disclosure generally discloses a three-dimensional (3D) image reconstruction capability. The 3D image reconstruction capability may be configured to support reconstruction of a 3D image of a scene. The 3D image reconstruction capability may be configured to support reconstruction of a 3D image of a scene based on lensless compressive image acquisition performed using a lensless compressive camera having a single aperture and a set of multiple sensors. The reconstructed 3D image of a scene may include (1) image data indicative of a set of multiple two-dimensional (2D) images reconstructed based on the set of multiple sensors of the lensless compressive camera (which may be represented as images) and (2) depth information indicative of depths at points or areas of an overlapping portion of the multiple images reconstructed based on the set of multiple sensors of the lensless compressive camera (which may be represented as a depth map).

摘要： Embodiments relate to a method and apparatus for super resolution video coding using compressive measurements. The method includes receiving, by a decoder, a set of measurements, where the set of measurements represents encoded video data having original video data with an original display resolution. The method further includes determining, by the decoder, a display resolution, where the display resolution is higher than the original display resolution, and determining a reduction matrix based on at least a number of pixels for the determined display resolution, where the reduction matrix includes a pattern of values. The method further includes reconstructing, by the decoder, the video data or a portion of the video data using the determined reduction matrix and the received set of measurements such that the original display resolution is enlarged to the determined display resolution.

摘要： In one aspect, a method for performing signal source localization is provided. The method comprises the steps of obtaining compressive measurements of an acoustic signal or other type of signal from respective ones of a plurality of sensors, processing the compressive measurements to determine time delays between arrivals of the signal at different ones of the sensors, and determining a location of a source of the signal based on differences between the time delays. The method may be implemented in a processing device that is configured to communicate with the plurality of sensors. In an illustrative embodiment, the compressive measurements are obtained from respective ones of only a designated subset of the sensors, and a non-compressive measurement is obtained from at least a given one of the sensors not in the designated subset, with the time delays between the arrivals of the signal at different ones of the sensors being determined based on the compressive measurements and the non-compressive measurement.

摘要： The present disclosure generally discloses block-based lensless compressive image acquisition capabilities. The block-based lensless compressive image acquisition capabilities may include a block-based lensless camera. The block-based lensless camera may include a set of two or more image acquisition block configured to capture respective sets of image data (e.g., detector outputs or compressive measurements produced from detector outputs) for respective image portions of an image to be captured by the block-based lensless camera. The blocks of a block-based lensless camera may each include an aperture including a set of aperture elements, a sensor, and an isolation chamber disposed between the aperture and the sensor for directing light from the aperture to the sensor while preventing comingling of light of the block and light of other blocks.
