Characteristic Analysis of Ofdm-Oqam System in Below Deck Ship Environment

Abstract

In today’s world ships plays vital role in transportation of people as well as heavy goods. So it is necessary to ensure the better
communication network in ships as it contains many decks and compartments. Ships may face many dangerous situation such as fog, change in weather, fire on ship. And also the communication is required for manual or automatic engine room and pilot on boarding. During that time, it is important to have a good communication between the deck officer and engine officer. But it is one of the most challenging thing in wireless communication. MIMO OFDM is a wireless communication method that is being developed for 5G. When we combine OFDM and MIMO, we get a significant boost in performance in terms of data transmission rate, bit error rate (BER), Signal to Noise Ratio (SNR), and dependability. In this research, we compare OFDM with OQAM using the OFDM structure to obtain good performance in terms of low BER and SNR through the use of superior channel coding techniques and modulation schemes. To decrease the effects of Inter Symbol Interference (ISI) generated by multiple reflections, orthogonal frequency-division multiplexing (OFDM) has been proposed. Using numerous antennas for channel diversity has also been found to improve communications reliability and capacity. The supplied PP-SNR figures demonstrate the increased dependability that space-time coding can bring. The estimation of Shannon channel capacity shows that spatial multiplexing can take use of multipath scattering to boost performance and throughput. An enhanced strategy for wireless communication employing intensity modulation scheme is examined in the suggested system, keeping modulation complexity and reaching high power as significant considerations. The suggested OFDM modulation technique incorporates the OQAM-OFDM structure and the BPSK structure, which have been compared and developed to show the improvements on wireless communications.
