Simulation of a New Algorithm to Enhance the Spectral Efficiency of 5G for IoT Applications

Abstract:
The wireless communication systems witness a huge developments in the mobile generations
(1G to 5G and recently 6G). These generations is available to satisfy the users need. The basic
goal of this paper is to simulate a 5G system in the physical layer for IoT applications. A
proposed model in this paper is a sensing system for various signals schemes at different noisy
channels. The model depends on new radio (NR) to work at high frequencies in wireless
communication applications and IoT applications. The design of the system was based on using
a variety types of modulation most commonly used in communication systems: OFDM, 8PSK
and MQAM. MATLAB simulation tools is used to implement the proposed system, where signals
of various lengths and different types of noise were taken. The noise types such as AWGN,
phase noise, frequency offset and Dc offset are applied to check the efficiency of the aimed
system. The proposed 5G system have been implemented in software by MATLAB simulation
tools to evaluate the results through constellation diagram, frequency spectrum and time scope
shows a good response. Obtained results from this work shows a good results in terms the
frequency spectrum and. constellation diagram. 5G is the attractive newest technology that
must to be studied in details, especially for communication engineers.
