Abstract : The research investigates approaches for estimating the Carrier Frequency Offset (CFO) and introduces the utilization of nature-inspired metaheuristic algorithms, such as the Firefly Algorithm, to enhance wireless communication settings. The adaptability of the Firefly Algorithm, combined with the proposed total ICI cancellation technique, presents promising opportunities for enhancing the performance of OFDM systems in the presence of intercarrier interference. In this paper, the authors delve into the challenges posed by Intercarrier Interference (ICI) in Orthogonal Frequency Division Multiplexing (OFDM) systems and explore various methods to overcome these challenges. They extensively review the existing literature on conjugate transmission techniques, total ICI cancellation strategies, self-cancellation schemes, and the effects of Doppler spreading. Keywords - Total ICI Cancellation, Wireless Communication, OFDM Systems, Spreading Code Matrix, Walsh Codes, Intercarrier Interference, Doppler Spreading, Self-Cancellation Schemes, Conjugate Transmission, Carrier Frequency Offset, Metaheuristic Algorithms, Firefly Algorithm
