摘要
AbstractThe performance of free space optical communication system using multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) with a modified receiver structure is evaluated in this paper referred to as MIMO-OFDM-FSO with the modified receiver (MIMO-OFDM-FSO-MR). Utilizing equal gain combining the analysis is done by taking closed-form expression of average bit error rate and throughput. The simulation is performed to estimate various performance parameters such as throughput and bit error rate (BER) for the proposed MIMO-OFDM-FSO-MR model under different turbulence and weather conditions. Simulation reveals that the proposed model exhibits significant BER performance and provides better throughput and spectral efficiency as compared with conventional FSO systems, OFDM-FSO systems, MIMO-FSO systems and Low-density Parity Check (LDPC) coded MIMO-OFDM-FSO systems.KEYWORDS: FSOGamma-Gamma modelIntegratorLDPCMIMOOFDMSchottky diode Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationNotes on contributorsChinmayee PandaChinmayee Panda is pursuing PhD in the Department of Electronics and Telecommunication Engineering, IGIT Sarang under Utkal University, India.
