Joint Target-Message Reception of Constant-Envelope CPM for Joint Radar and Communications [PDF]

open access: yesSensors
This paper presents a likelihood-consistent joint target-message receiver for a strictly constant-envelope continuous phase modulation (CPM) waveform in pulsed phased-array joint radar–communication (JRC). Station A performs monostatic detection with the

Serially Concatenated Schemes for Single Sideband Continuous Phase Modulation

open access: yesIEEE Open Journal of the Communications Society, 2023
This paper investigates serially concatenated (SC) and interleaved transmission schemes for a new class of continuous phase modulation (CPM), which has the property being a single sideband (SSB). This new CPM is commonly called Single Side-Band Frequency

Phase Noise Resilient Three-Level Continuous-Phase Modulation for DFT-Spread OFDM

open access: yesIEEE Open Journal of the Communications Society, 2022
In this paper, a novel waveform with low peak-to-average power ratio (PAPR) and high robustness against phase noise (PN) is presented. It follows the discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) signal model ...

1.8 m/0.5 s Resolution Coherent Doppler Wind Lidar Using Continuous Phase Modulation

open access: yesIEEE Photonics Journal, 2022
A high-spatial-resolution coherent Doppler wind lidar (CDWL) with high modulation efficiency is reported. The pseudo-random phase coding (PRPC) links the spatial resolution to the modulation rate but suffers from the non-rectangular transition caused by ...

Optimal Parameter Design of Continuous Phase Modulation for Future GNSS Signals

open access: yesIEEE Access, 2021
Continuous phase modulation (CPM) is a power and spectrum efficient modulation that intrinsically possesses constant envelope, phase continuity as well as less out of band (OOB) radiation, especially appropriate for stringently bandwidth-constrained ...
