Abstract

Orthogonal Frequency Division Multiplexing (OFDM) is used to enhance Bit Error Rates (BER) performance for error free transmission in free space in free pace. OFDM-based systems operate in the hostile multipath radio environment, which allows efficient sharing of limited resources. This research work was designed, developed and simulated an FFT-OFDM based System using the basic blocks of Simulink in MATLAB/Simulink software, to enhance BER for error free transmission. The system was design using Fast Fourier transform (FFT) and Inverse Fast Fourier transform (IFFT). This was achieved in backing of collection and review of high-quality research papers, which reported the latest research developments in OFDM communications networks, and its applications in future wireless systems. The research mitigated the noise enhancement effect. And many critical problems associated with the error transmission in wireless communication networks in the future. An error transmission in wireless systems is global issues and challenges that are still looking for efficient solutions. This research work would overcome the global issues and challenges facing the wireless communication network.
