Patent number: 9703260Abstract: Methods and devices for coherent holographic data channel techniques. Coherent techniques for data detection generally include homodyne and heterodyne detection. Techniques for quadrature homodyne detection, resampling quadrature homodyne detection, n-rature homodyne detection, and spatial wavefront demodulation. Coherent detection techniques in turn enable coherent channel modulation techniques such as phase modulation (including binary phase shift keying, or BPSK; phase quadrature holographic multiplexing, or QPSK; and quadrature amplitude modulation, or QAM). Coherent detection may also enable or improve the performance of other channel techniques such as partial response maximum likelihood (PRML), the various classes of extended PRML, and of noise-predictive maximum likelihood (NPML) detection.Type: GrantFiled: August 20, 2015Date of Patent: July 11, 2017Assignee: Akonia Holographics LLCInventors: Mark R. Ayres, Kenneth E. Anderson, David C. Pruett, Will A. Loechel

Publication number: 20150070739Abstract: Methods and devices for coherent holographic data channel techniques are presented. Coherent techniques for data detection generally include homodyne and heterodyne detection. Techniques for Quadrature homodyne detection (QHD), Enhanced resampling quadrature homodyne detection (ERQHD), N-rature homodyne detection (NHD), and local oscillator fringe demodulation are presented. Coherent detection techniques in turn enable coherent channel modulation techniques such as phase modulation (including binary phase shift keying, or BPSK; phase quadrature holographic multiplexing, or QPSK; and quadrature amplitude modulation, or QAM). Coherent detection may also enable or improve the performance of other channel techniques such as Partial response maximum likelihood (PRML), the various classes of extended PRML, and of Noise predictive maximum likelihood (NPML) detection.Type: ApplicationFiled: September 11, 2014Publication date: March 12, 2015Inventors: Mark R.
