Abstract:
The rapid advancements in modern communication systems demand robust, scalable wireless networks. This paper investigates the design and performance analysis of a 5G LTE physical layer based on Orthogonal Frequency Division Multiplexing (OFDM). A simulation model is developed in MATLAB/Simulink to evaluate Bit Error Rate (BER) performance under Additive White Gaussian Noise (AWGN) and multipath Rayleigh fading channels. Advanced modulation schemes such as BPSK, QPSK, and QAM are implemented with adaptive decision control to improve spectral efficiency. The study demonstrates that effective channel estimation and adaptive modulation significantly enhance system reliability in dynamic wireless environments. These results contribute to the development of practical high-speed broadband access, particularly for urban and rural applications where traditional wired infrastructure is not feasible.
