In cellular network technology, the Long Term Evolution (LTE) standard has been developed to improve data transmission, providing greater throughput and lower latency. To adapt to various channel conditions and to increase data rates, the LTE standard uses different modulation schemes (such as QPSK, 16-QAM, and 64-QAM). This project presents an overview of the Bit Error Rate (BER) performance under different modulation schemes in an LTE digital communication system. Extensive simulation results show that a turbo channel coded LTE system performs much better in terms of BER than the non-coded model at various SNR levels. The simulations also show that in both non-coded and turbo-coded systems, the less dense the constellation modulation scheme is, the better its BER performance will be.
