Amplitude encoded phase-only filters

Applied Optics, 1989
The phase-only filter (POF) and binary phase-only filter (BPOF) have been shown to have high optical efficiency, good target discrimination, and virtually no sidelobes. We present a simple method of amplitude encoding the signal phase information. These new filters have most of the same advantages of a POF or BPOF so that amplitude modulating spatial ...

Amplitude-smoothed BPOF and amplitude-smoothed amplitude-encoded BPOF

SPIE Proceedings, 1990
In this paper smoothed binary phaseonly filtcr(ASBPOF) and amplitude smoothed amplitude encoded BPOF(ASAEBPOF) are presented. By computer simulation in the case of symmetrical and unsymmetrical characters it is concluded that with the BPOF and AEBPOF these filters sacrifice light efficiency due to the amplitudesmoothed factor it yield much better ...

Amplitude-encoded calcium oscillations in fish cells

Biophysical Chemistry, 2011
The reaction of intracellular Ca(2+) to different agonist stimuli in primary hepatocytes from rainbow trout (Oncorhynchus mykiss) as well as the permanent fish cell line RTL-W1 was investigated systematically. In addition to "classical" agonists such as phenylephrine and ATP, model environmental toxicants like 4-nitrophenol and 3,4-dichloroaniline were

Amplitude adaptive ASDM without envelope encoding

2016 24th European Signal Processing Conference (EUSIPCO), 2016
In this paper a method of encoding the signals by using Amplitude Adaptive Asynchronous Sigma-Delta modulator (AA-ASDM) scheme without an additional envelope encoding of the signal is proposed. According to AA-ASDM, the time-varying envelope function of the input signal is used in the feedback loop to reduce the switching rate of the output trigger and

Blended source imaging by amplitude encoding

SEG Technical Program Expanded Abstracts 2010, 2010
The computational cost of conventional imaging is large for today’s wide-azimuth seismic surveys. One strategy to reduce the overall cost of seismic imaging is to migrate with multiple shot-gathers at once, a technique which is known as blended source imaging.

Amplitude Encoded Binary Phase-Only Filters

SPIE Proceedings, 1988
The phase-only (POF) and binary phase-only (BPOF) filter have been shown to have high optical efficiency, good target discrimination, and virtually no sidelobes. We present a simple method of encoding phase information in an amplitude mode that has the same advantages of a POF or BPOF so that amplitude modulating SLMs can be used.

Differential Encoding for Quadrature-Amplitude Modulation

2010 IEEE 71st Vehicular Technology Conference, 2010
In this paper, we propose a novel differential encoder for QAM (quadrature-amplitude modulation), by a look-up table instead of a rule. Using a table for differential encoding has the advantages of both low complexity and good error performance. We propose algorithms to construct the table for maximizing the minimum noncoherent distance and minimizing ...

ENCODING CARRIER AMPLITUDE MODULATIONS VIA STOCHASTIC PHASE SYNCHRONIZATION

International Journal of Bifurcation and Chaos, 2000
The firings of excitable systems can phase lock to periodic forcing. In many situations however, the firings are separated by a random number of forcing cycles, even though they occur near a preferred phase of the forcing. Also, the associated interspike interval histograms display peaks over a continuous range of integer multiples of the forcing ...

Trellis encoding of continuous-amplitude memoryless sources (Corresp.)

IEEE Transactions on Information Theory, 1977
Trellis coding of analog memoryless sources with respect to the squared-error distortion criterion is investigated via simulation. Sources treated are the Gaussian, uniform, Laplacian, and Gaussian mixture models, and the encoding algorithms studied are the Viterbi and M algorithms.
