Optimum operation of future mobile communication systems requires more flexible
signalling mechanisms for radio access. For flexible heterogeneous signalling …

With the cross-fertilization development of automatic control technology, electronic science
and technology, and wireless communication technology, a single filter is no longer able to …

Compared to orthogonal frequency division multiplexing (OFDM), spectrally efficient
frequency division multiplexing (SEFDM) provides higher spectrum efficiency, which has …

Telemedicine is a promising direction in the development of medical technologies for the
interaction of patients with doctors at a distance. In this paper, we consider the use of …

This paper proposes a novel ultra-dense non-orthogonal frequency-division multiplexing
(NOFDM) transmission, where subcarrier spacing is set significantly lower than that of …

We propose and demonstrate continuously tunable frequency synthesis over 5–170 GHz
using phase locked narrow linewidth lasers. Phase locking over a wide frequency range is …

In this article, a joint symbol timing offset (STO) and Doppler frequency offset (DFO)
estimation algorithm is proposed for spectrally efficient frequency division multiplexing …

A unique automatic receiver signal distribution strategy is proposed for private optical
networks based on the concept of non-orthogonality. A non-orthogonal signal waveform can …

This study models and analyses the fabrication errors of an ultra-wideband (UWB) Schottky
