Effects of Various Digital Modulation Methods on LTE System Over Orthogonal Frequency Division Multiplexed AWGN : A Review

This research includes a comprehensive analysis and comparison of all conceivable modulation methods that LTE systems may use over an OFDM AWGN channel. Given that this is of the highest importance when constructing wireless communication systems, this research gives the modulation strategy with the lowest bit error rate and investigates whether it is capable of giving the necessary data rate in LTE systems. This study offers a low-bit error rate modulation technique and evaluates its ability to provide the data rates required by LTE networks. The authors of this paper provide a fresh approach to computing the handover margin and call loss rate in LTE-based networks. OFDM is used in LTE to achieve modulation. With this technique, several users may share a single channel while yet preserving the spectral efficiency necessary for large data rates. A single channel is divided into several smaller subcarriers using OFDM. LTE must be considered in terms of its value and dependability. The handover rate and call drop rate are measures of the efficiency and dependability of LTE. When a mobile device switches from one cell service area to another during an LTE handover, the user's established session must continue uninterrupted. The proportion of all unsuccessful calls is known as the call dropping rate. The connection speed of the user affects call drop and HOM. Better LTE solutions are anticipated to be a key result of this kind of research.
