LTE Modulation and Coding Schemes for 6G Networks

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.
