Study of Different Denoising Methods for Underwater Acoustic Signal

Marine Engineering faces certain challenges in recent times due to the prevalence of ambient conditions caused by imbalance in the ecosystem. Underwater ambient noise is primarily a background noise, which is a function of time, location and depth. It is of prime importance to detect the signals such as the sound of a submarine or an echo from a target, surpassing and surmounting this ambient n...

Multi-Objective Learning Automata for Design and Optimization a Two-Stage CMOS Operational Amplifier

In this paper, we propose an efficient approach to design optimization of analog circuits that is based on the reinforcement learning method. In this work, Multi-Objective Learning Automata (MOLA) is used to design a two-stage CMOS operational amplifier (op-amp) in 0.25μm technology. The aim is optimizing power consumption and area so as to achieve minimum Total Optimality Index (TOI), as a new...

Cross-Layer Design For Energy-Efficient In Wireless Underwater Communication: Acoustic Frequency IDentification Case Study

Thanks to the recent developments on communication techniques, micro-technology and on digital electronics, Underwater Wireless Sensor Networks (UWSNs) are being employed in several types of underwater applications such as wireless identification named Acoustic Frequency Identification (AFID)[1][2]. In this research, we are trying to adapt concepts of wireless acoustic identification to the dif...
