Summary: | Orthogonal frequency division multiplexing (OFDM) stands as a pivotal technology across a multitude of wireless standards, solidifying its significance in various application deployments. This paper aims to ascertain the ergodic capacity of an OFDM system operating in conjunction with diverse wireless channels, spanning from simpler models such as Rayleigh and Rician to more intricate models like Nakagami-m and alpha - mu channels, respectively.
In the pursuit of harnessing the potential of the emerging sixth-generation (6G) terahertz (THz) domain, the expansive bandwidth inherent to THz bands emerges as a pivotal asset, spanning from tens of gigahertz (GHz) upwards to several THz, contingent upon transmission distance. Within this burgeoning landscape, the alpha - mu channel model has surfaced as a promising framework for encapsulating the intricacies of THz spectrum in wireless communications. Notably, its efficacy lies in its demonstrated capacity to align closely with empirical field data, thereby underpinning its suitability for practical application and analysis within real-world contexts.
Consequently, contemporary modulation schemes leverage OFDM technology to showcase the innate capabilities of OFDM and to offer insights into how OFDM can effectively address the forthcoming challenges inherent in the THz spectrum. This exploration, rooted in empirical simulations and theoretical frameworks, endeavors to furnish valuable perspectives on the adaptability and resilience of OFDM systems. |
