“…The notion of SDR is to use software as much as possible for implementing communication modules. A typical SDR platform consists of two components [23]: a general purpose programmable platform for signal processing in baseband level and peripheral equipment for frequency conversion and digitalization.…”

The fifth generation (5G) New Radio (NR) has been developed to provide significant improvements in scalability, flexibility, and efficiency in terms of power usage and spectrum as well. To meet the 5G vision, service and performance requirements, various candidate technologies have been proposed in 5G new radio; some are extensions of 4G and, some are developed explicitly for 5G. These candidate technologies include non-Orthogonal Multiple Access (NOMA), and Low Density Parity Check (LDPC) channel coding. In addition, deploying software defined radio (SDR) instead of traditional hardware modules. In this paper we build an open source SDR-based platform to realize the transceiver of the physical downlink shared channel (PDSCH) of 5G NR according to Third Generation Partnership Project (3GPP) standard. We provide a prototype for pairing between two 5G users using NOMA technique. In addition, a suitable design for LDPC channel coding is performed. The intermediate stage of segmentation, rate matching and interleaving are also carried out in order to realize a standard NR frame. Finally, experiments are carried out in both simulation and real time scenario on the designed 5G NR for the purpose of system performance evaluation, and to demonstrate its potential in meeting future 5G mobile network challenges.

“…However, the design and implementation of a digital receiver requires a significant level of communication theory and SDR implementation proficiency [1,13,3,7]. Moreover, such implementation has to be delayed until the students have gained sufficient knowledge in communication theory, for example, orthogonal frequency‐division modulation (OFDM) [18]. The mitigation of channel‐related impairments, such as OFDM frequency‐time pilot schemes and channel equalization, are an inherent part of such an implementation.…”

One of the important aspects in the study of wireless communication is channel modeling that is based on wave propagation theory and empirical measurements models. Most of the common undergraduate curricula address only theoretical aspects of wireless channels, while the related laboratory experiments concentrate on advanced digital modulation techniques and deal with topics such as pilot‐based channel estimation and equalization in orthogonal frequency division multiplexing modulation. In this paper, it is shown that some fundamental channel properties may be reproduced with laboratory experiments that require only a basic knowledge of communication principles, such as baseband and bandpass notation. These experiments can be carried out with affordable software‐defined radios, which have recently become extremely popular in the teaching of communication. Such experiments may enhance the teaching with hands‐on measurements of practical channels, while reinforcing the understanding of probability and random processes theory.

“…Electromagnetism is a subject with the aforementioned characteristics. Instructors have been actively experimenting with approaches to make electromagnetism education more interesting and easy to understand . Carpenter of Imperial College, who uses finite difference models to approach field distribution using computer plots , was one of the earliest educators to use CAI in computer‐based electromagnetics education.…”

“…For example, Aydin and her team proposed a course that support student modeling and design of microwave components by means of computer tools, design fabrication, and design measurements . A more complex experimental platform, which is a real‐time Wi‐Fi laboratory platform on USRP and LabVIEW for wireless communications education and research , is proposed by another university in Turkey, and students have a more complete understanding of the architecture of wireless communication systems through such experimental platforms.…”

Computers and multimedia technology can greatly facilitate the visualization of abstract concepts and intangible objects such as electromagnetic waves. An educational design platform is proposed to assist undergraduate students in understanding these waves. At present, most electromagnetics courses still use traditional teaching design ideas, from mathematics to reason, and spend much time on formula deduction. Educational design overturns this idea thoroughly to learn with problems and solve experiments related to uncertain concepts; this design will help undergraduate students learn the basic characters of electromagnetic waves intuitively and more easily. Through the experiment‐simulation method, students can experimentally sample data and process data real‐time using simulation software. In this way, students can grasp the physical meaning of abstract concepts more accurately through experiments; furthermore, computer simulations can show the relationships between parameters more intuitively. Thus, the original intention of teaching aided design is exactly reflected: “see knowledge and learn knowledge.”
