Abstract
Background: Long-term evolution (LTE) is the fourth generation (4G) mobile communication
technology developed by the 3rd Generation Partnership Project (3GPP). In comparison to previous
generations of cellular systems, LTE incorporates several innovative technologies. These innovative
technologies are used to increase spectrum efficiency and data speeds, as envisioned by designers.
Methods: This study provides a comprehensive investigation of orthogonal frequency division multiple
access and the single carrier frequency division multiple access transmission model and investigates
the physical layer performance of the LTE system using a MATLAB-Simulink environment.
Results: By providing spectrum flexibility, the SC-FDMA-OFDMA 16 QAM with the AWGN channel
transmission model achieves a higher outcome and has a packet loss rate of 0%. The numerical
evaluation is used to illustrate the trade-off between loss of capacity in the time and frequency domains.
Conclusion: SC-FDMA has a lower multipath propagation rate and peak to average power ratio than
OFDM; therefore, multipath must be eliminated to make it more efficient. The final section of this
study contains a full description of the techniques required to simulate a simple communication model.
