QUASIORTHOGONAL FREQUENCY ACCESS ON SUBCARRIER FREQUENCIES
Advanced Information Systems, 2019 In the article, it is described the principles of implementing the method based on quasiorthogonal frequency access on subcarrier frequencies. The key element of quasiorthogonal frequency access on subcarrier frequencies is the using of the individual distribution of frequency subcarriers in different frequency plans of the ensemble in the general ...

Frequency synchronization induced by frequency detuning
Science AdvancesIt is widely held that identical systems tend to behave similarly under comparable conditions. Yet, for systems that interact through a network, symmetry breaking can lead to scenarios in which this expectation does not hold. Prominent examples are chimera states in multistable phase-oscillator networks.
