MIMO - OFDM System Based Wireless Data Transmission in Underwater Hydroacoustic Environment

The capability of bandwidth or spectrum, or both at the same time should be altered to improve the transmission rate of wireless transmission systems. A MIMO system has the potential to significantly enhance spectrum usage. When MIMO and OFDM are combined, wireless networks can handle higher data rates. Adaptive space-time signal processing methods with spatial filtering can be used to lessen the impact of multipath propagation under the challenging imaging conditions of transmitting data over a wireless channel. Because of the huge number of transmitters and receivers utilized in MIMO, transmission speeds may be improved. Three low-complexity adaptive equalization designs for data rates, as well as the utilization of space-time trellis codes (STTCs), layered space-time codes (LSTCs), and their combinations were investigated in this research work.
