Various approaches are presented in order to accommodate 9. 6 kb/s modem signals (e.g., V.29) through 32 kb/s ADPCM links.

The limited ability of medium rate (16 kb/s) speech coders to accommodate voiceband data signals may ultimately limit their application in switched telecommunications networks.

Sub-Terahertz (sub-THz) communication is a key enabling technology to deliver ultra-high rates up to Terabit/s - one of 6G envisioned goals.

In this paper we review the waveform design of 4G (based on OFDM) and motivate the need for a redesign for 5G.

In this paper we compare three candidate multicarrier waveforms for the air interface of 5G: CP-OFDM - the choice for 4G, FBMC - heavily discussed in recent years, and Universal Filtered Multi-Carr

The next-generation cellular network is to provide a large variety of services for different kinds of terminals, from traditional voice and data services over mobile phones to small packet transmis

We propose a learning-based method for the joint design of a transmit and receive filter, the constellation geometry and associated bit labeling, as well as a neural network (NN)-based detector.

The projected sub-THz from 100 to 300 GHz as part of the upcoming 6G standard will require a careful design of the waveform and choice of frame structure.

We report experimental studies of the optical properties of two-dimensional low index-contrast AlGaAs-based photonic crystal waveguide structures.

Avalanche photodiodes (APDs) are key components for future optical transmission systems because their internal gain provides better sensitivity.
