Digital holography enables quantitative phase imaging based on interference. A digital hologram often encodes the phase information along with aberrations or deformations. This article reviews phase ...

Abstract: A continuous phase modulation (CPM) implementation alternative of a recently standardized class of Feher-patented quadrature phase-shift keying (FQPSK-B) modulation is proposed. It is based ...

Abstract: We develop a coded modulation system with continuous phase and a small controlled envelope variation. We call the system constrained envelope continuous phase modulation (ceCPM) and show ...
