Abstract

OFDM or orthogonal frequency-division is one of those concepts that have been percolating for a long time and finally materialized when mass market applications appeared at the same time as efficient software and electrical technologies were widely available. This article provides an overview of the history and early development of OFDM, as well as an explanation of the reasons for using it. Offset frequency-division multiplexing (OFDM) is a kind of frequency-division multiplexing (FDM) in which adjacent sub-channels do not interfere with one another. However, the computing approach known as the fast Fourier transform (FFT) of the discrete Fourier transform (DFT) is not required. For OFDM, this research uses the Universal Verification Methodology to validate the Backward Fourier Transform (IFFT), the feasible technique, and the QPSK algorithms. The IEEE 1800 standard for UVM guides developing a setting conducive to verifying elaborate designs. The UVM verification developed for this project is portable, meaning it may be used to check algorithms utilized by other FDM techniques.
