Spectral Optimization For Communication Under A Peak Frequency-Domain Power Constraint

View page
US Patent:
6839429, Jan 4, 2005
Filed:
Mar 10, 1999
Appl. No.:
09/266413
Inventors:
Rohit V. Gaikwad - Houston TX, US
Richard G. Baraniuk - Houston TX, US
Assignee:
WM. Marsh Rice University - Houston TX
International Classification:
H04M 176
H04M 700
H04M 900
US Classification:
379417, 379416, 379 9301, 379282, 379286, 370201, 375296
Abstract:
System and methods for determining an optimized transmit spectra (spectral distributions of transmission power) for a set of communications channels that experience cross-talk among themselves and for transmitting data on the channels. The transmit spectra are preferably constructed so that largely contiguous frequency bands are allocated to each signaling direction (upstream/downstream) on each communications channel and/or to each channel in the set of channels. In one embodiment, each communications channel is restricted to a maximum time-averaged power. The method preferably includes steps of determining the channel transfer functions of the communications channel, determining interference characteristics of the channels, calculating substantially optimal transmit spectra for the communications channels, and redistributing the frequency bins so that they are contiguously grouped in each transmit spectra. The contiguous groupings allow wider frequency bands for signaling in the channel. In one embodiment, the channel is limited by a “peak-power constraint. ”.

US Patent:
7035400, Apr 25, 2006
Filed:
Feb 21, 2000
Appl. No.:
09/510966
Inventors:
Rohit V. Gaikwad - Houston TX, US
Richard G. Baraniuk - Houston TX, US
Assignee:
Wm. Marsh Rice University - Houston TX
International Classification:
H04M 1/76
H04M 7/00
H04M 9/00
US Classification:
379417, 37939201, 379416, 379 103, 370201, 370298, 375222, 375227
Abstract:
An improved system and method for communicating information on a transmission medium is disclosed. The disclosed system and method provide improved communications on the transmission medium in the presence of interference, which may take the form of uncorrelated interference from different services on neighboring transmission mediums. In one embodiment, the communications system includes a subscriber modem, a central office modem; and a communications channel coupled between the subscriber modem and the central office modem. The communications channel transports uplink signals from the subscriber modem to the central office modem, and downlink signals from the central office modem to the subscriber modem. At frequencies below a selected frequency M, the power spectral density of the transmitted uplink signals is proportional to the power spectral density of the transmitted downlink signals by a positive scale factor, and at frequencies above M, the power spectral density of the uplink signals is limited to one or more uplink frequency bands and the power spectral density of the downlink signals is limited to one or more downlink frequency bands that are disjoint from the uplink frequency bands. Preferably, the total bandwidth of the uplink frequency bands above Mis proportional to the total bandwidth of the downlink frequency bands above Mby the same positive scale factor.

Analog System For Computing Sparse Codes

View page
US Patent:
7783459, Aug 24, 2010
Filed:
Feb 21, 2008
Appl. No.:
12/035424
Inventors:
Christopher John Rozell - El Cerrito CA, US
Don Herrick Johnson - Houston TX, US
Richard Gordon Baraniuk - Houston TX, US
Bruno A. Olshausen - San Francisco CA, US
Robert Lowell Ortman - Houston TX, US
Assignee:
William Marsh Rice University - Houston TX
International Classification:
G06F 19/00
US Classification:
702189, 702 71, 341 87, 341 50, 714801, 714746, 714758, 37524016, 37524022, 382253
Abstract:
A parallel dynamical system for computing sparse representations of data, i. e. , where the data can be fully represented in terms of a small number of non-zero code elements, and for reconstructing compressively sensed images. The system is based on the principles of thresholding and local competition that solves a family of sparse approximation problems corresponding to various sparsity metrics. The system utilizes Locally Competitive Algorithms (LCAs), nodes in a population continually compete with neighboring units using (usually one-way) lateral inhibition to calculate coefficients representing an input in an over complete dictionary.

Apparatus And Method For Compressive Sensing Radar Imaging

View page
US Patent:
7928893, Apr 19, 2011
Filed:
Apr 12, 2007
Appl. No.:
12/296627
Inventors:
Richard G. Baraniuk - Houston TX, US
Theo P. H. Steeghs - Ilfov, RO
Assignee:
William Marsh Rice University - Houston TX
International Classification:
G01S 13/00
US Classification:
342 25F, 342179
Abstract:
Method and apparatus for developing radar scene and target profiles based on Compressive Sensing concept. An outgoing radar waveform is transmitted in the direction of a radar target and the radar reflectivity profile is recovered from the received radar wave sequence using a compressible or sparse representation of the radar reflectivity profile in combination with knowledge of the outgoing wave form. In an exemplary embodiment the outgoing waveform is a pseudo noise sequence or a linear FM waveform.

Method And Apparatus For Compressive Imaging Device

US Patent:
8199244, Jun 12, 2012
Filed:
Jun 1, 2010
Appl. No.:
12/791171
Inventors:
Richard G. Baraniuk - Houston TX, US
Dror Z. Baron - Cary NC, US
Marco F. Duarte - Durham NC, US
Kevin F. Kelly - Houston TX, US
Courtney C. Lane - Ventura CA, US
Jason N. Laska - Houston TX, US
Dharmpal Takhar - Houston TX, US
Michael B. Wakin - Castle Rock CO, US
Assignee:
William Marsh Rice University - Houston TX
International Classification:
H04N 5/225
US Classification:
348335, 348344
Abstract:
A new digital image/video camera that directly acquires random projections of the incident light field without first collecting the pixels/voxels. In one preferred embodiment, the camera employs a digital micromirror array to perform optical calculations of linear projections of an image onto pseudorandom binary patterns. Its hallmarks include the ability to obtain an image with only a single detection element while measuring the image/video fewer times than the number of pixels or voxels—this can significantly reduce the computation required for image/video acquisition/encoding. Since the system features a single photon detector, it can also be adapted to image at wavelengths that are currently impossible with conventional CCD and CMOS imagers.
