The deviation of continuous and discrete complex random variables from the traditional
proper and symmetric assumption to a generalized improper and asymmetric …

Modern wireless communication systems are expected to provide improved latency and
reliability. To meet these expectations, a short packet length is needed, which makes the first …

In this paper we propose a multiple importance sampling (MIS) method for the efficient
symbol error rate (SER) estimation of maximum likelihood (ML) multiple-input multipleoutput …

A study of interference management in a Single-Input-Single-Output (SISO) two-user
broadcast scenario by adjusting the circularity coefficient of discrete constellations is …

Variational autoencoders are deep generative models that have recently received a great
deal of attention due to their ability to model the latent distribution of any kind of input such …

Hardware non-idealities are among the main performance restrictions for upcoming wireless
communication systems. Asymmetric hardware distortions (HWD) happen when the …

Digital constellations formed by hexagonal or other non-square two-dimensional lattices are
often used in advanced digital communication systems. The integrals required to evaluate …

This paper addresses the problem of designing asymptotically optimal improper
constellations with a given circularity coefficient (correlation coefficient between the …

An end-to-end testbed for In-phase and Quadrature (I/Q) Imbalance (IQI) communication
systems based on Software-Defined Radio (SDR) is presented. The scenario under …

The fifth-generation cellular network requires dense installation of radio base stations (BS)
to support the ever-increasing demands of high throughput and coverage. The ongoing …
