        abstract = {WiMAX (Worldwide Interoperability for Microwave Access), standardized by IEEE 802.16e, is a promising solution for providing high-speed broadband wireless access, especially in last-mile connectivity scenarios. Its physical layer employs Orthogonal Frequency Division Multiplexing (OFDM) and Multiple-Input Multiple-Output (MIMO) techniques to ensure robust performance in multipath and non-line-of-sight (NLOS) conditions. This paper presents an in-depth study of the WiMAX physical layer, exploring how MIMO-OFDM and adaptive modulation and coding schemes (AMC) enhance system capacity, spectral efficiency, and link reliability. The paper also analyses key performance metrics through simulation results, demonstrating the significant benefits of integrating MIMO diversity and dynamic modulation schemes. These insights offer practical guidance for optimizing WiMAX networks under varying channel conditions.},
