Design and Performance of Constrained Envelope Continuous Phase Modulation [PDF]
, 2009 We have developed a coded modulation system with continuous phase and a small controlled envelope variation called Constrained Envelope Continuous Phase Modulation (ceCPM). For the spectrally efficient scenarios, within the ceCPM framework it is possible

Improving radar performance with constant envelope multi-level chirp
Tehnički Glasnik, 2019 M-level Continuous Phase Chirp Modulation is considered for data transmission. In this article, we would like to propose a new approach to transmitting information with the help of multi-level wave guide signaling. The main problem with the classic chirp

Continuous-Phase, Unmodulated Parallel-Combinatory High-Compaction Multicarrier Modulation [PDF]
, 2011 A new type of modulation called continuous-phase parallel-combinatory high-compaction multicarrier modulation (CPPC/HC-MCM) is proposed. CPPC/HC-MCM employs the technique of continuous-phase modulation (CPM) and avoids the formation of amplitude gaps ...

Spectrally Efficient Continuous Phase Modulation [PDF]
, 2002 Spectrally efficient continuous phase modulation (CPM) systems and generalizations of CPM for wireless links are considered. Continuous phase modulation defines constant envelope phase codes, which are advantageous when using non-linear amplifiers.

Cooperative diversity with continuous phase modulation [PDF]
Turkish Journal of Electrical Engineering and Computer Sciences, 2011 In recent years, there has been a vast amount of research on cooperative diversity due to its potential capacity increase. Almost all of the research has been based on linear modulation formats such as phase-shift keying (PSK) or quadrature amplitude ...

Phase-Modulation-Mode-Locked Continuous-Wave MgO:PPLN Optical Parametric Oscillator
IEEE Photonics Journal, 2015 We report phase-modulation mode-locking of a continuous-wave (cw) singly-resonant optical parametric oscillator (OPO) in the near- and mid-infrared based on MgO-doped periodically poled LiNbO3 (MgO:PPLN) and pumped by an Yb-fiber laser at 1064 nm.
