Abstract: Detection of endogenous metabolites using multiplexed editing substantially improves the efficiency of edited magnetic resonance spectroscopy. Multiplexed editing (i.e., performing more than one edited experiment in a single acquisition) requires a tailored, robust approach for…

Abstract: Abstract We theoretically analyzed and experimentally demonstrated the feasibility of optical single sideband (OSSB) signal generation based on multi-frequency phase modulation. The numerically calculated results show that OSSB signal can be efficiently generated with the…

Abstract: BACKGROUND Mixed frequency and phase coding (FPC) can achieve the significant increase of the number of commands in steady-state visual evoked potential-based brain-computer interface (SSVEP-BCI). However, the inconsistent phases of the SSVEP over channels in…

Abstract: An entangled photon experiment has been performed with a large variation of the temperature of the non-linear crystal generating the entangled pair by spontaneous downconversion. The photon pairs are separated by a nonpolarizing beamsplitter, and…

DOI: 10.1109/lpt.2020.3006881
Abstract: A photonics-based approach to multi-frequency phase-coded microwave signal generation is proposed with an increased number of frequencies. Two microwave reference signals are sent to one arm of a dual-drive Mach-Zehnder modulator (DD-MZM), whereas the binary…

Abstract: In space communications, there exist two prominent issues: large Doppler spread and limited pilot resources, which will result in poor performance for a pilot-aided (PA) traditional carrier synchronization mode (TCSM) with serial processing. In view…

Abstract: Tracking of signal frequency and/or phase is made much more challenging by the presence of “rapid” frequency or phase changes in a signal—occurring in a time short compared to the amount of frequency shift: Δf×Δt

Abstract: A new frequency-to-phase mapping technique for measuring a radio-frequency (RF) signal frequency is presented. The concept is based on generating two low-frequency signals where their phase difference is dependent on the input RF signal frequency.…
