This article reviews the main parts of a software-defined radio (SDR) to emphasize several
possible implementations of both receivers and transmitters. We describe solutions for …

A new function split option for the next generation fronthaul interface (NGFI) is demonstrated
based on all-digital RF transmitter using bandpass delta-sigma modulation. Different from …

We first experimentally demonstrated a digital mobile fronthaul (MFH) architecture using
delta–sigma modulation as the new digitization interface to replace the conventional …

Distributed multiple-input-multiple-output (DMIMO) is a very promising technique to improve
capacity and quality of service for emerging 5G systems. In this paper, we propose a flexible …

Power efficiency is one of the most important parameters in designing communication
systems, especially battery operated mobile terminals. In a typical transceiver, most of the …

This paper briefly presents software defined radio (SDR) concept and layouts an overview of
the actual state-of-the-art solution for power amplification systems and software enabled …

All-digital outphasing transmitter architecture using multidimensional power coding (MDPC)
is proposed for noncontiguous concurrent multiband transmission with a high power …

This paper proposes a new closed-form expression for computing the power efficiency of
delta-sigma (DS) radio frequency (RF) transmitters. Due to the large bandwidth of the …

All-digital transmitters are getting increased attention due to its closer proximity to the ideal
software-defined radio (SDR) transmitter. In this paper we propose a new transmitter …

This paper presents a new all-digital transceiver architecture fully integrated into a single
field-programmable gate array chip. Both the radio frequency (RF) receiver and the …
