TL;DR: In this paper, a single-chip 110-170-GHz ( $D$ -band) direct conversion in-phase/quadrature-phase (I/Q) transmitter (TX) and receiver (RX) monolithic microwave integrated circuits (MMICs), realized in a 250-nm indium phosphide (InP) double heterojunction bipolar transistor (DHBT) technology, is presented.

TL;DR: In this article, a new optical spectrally efficient frequency division multiplexing technique, utilizing coherent detection and polarization detection, was proposed and demonstrated, using non-orthogonal and overlapping subcarriers to provide a significant reduction in both electrical and optical bandwidth.

TL;DR: In this paper, a new chaotic jerk circuit was realized using a current-tunable technique based on traditional nonlinearity of a signum function, and newly smooth transitions from a balanced double-scroll chaotic jerk attractor to an unbalanced double- scroll and eventually to either a left-half or a right-half single-wheel chaotic jerk magnet attractor were experimentally revealed using either a negative or a positive adjustable current source I 0, respectively.

TL;DR: In this article, a new method for emulating array coupling influence on RF power amplifiers in a measurements setup is presented, based on an iterative procedure, where a signal is injected towards the output of the power amplifier, according to the output signal of a power amplifier measured in the previous iteration.

TL;DR: This paper shows the highest transmission rate of 12 Gb/s over a bandwidth varying between 2.67 to 4 GHz depending on the compression level of the SEFDM signals, which results in a spectral efficiency improvement by up to 50%, compared to the conventional orthogonal frequency division multiplexing modulation format.
