A Novel System to Increase Yield of Manufacturing Test of an RF Transceiver through Application of Machine Learning
Siddiqui, Atif Ahmed; Otero-Roth, Pablo; Zubair, Muhammad (IOAP-MDPI, 2023-01-08)Electronic manufacturing and design companies maintain test sites for a range of products. These products are designed according to the end-user requirements. The end user requirement, then, determines which of the proof ... -
Ciphered BCH Codes for PAPR Reduction in the OFDM in Underwater Acoustic Channels
Murad, Mohsin; Tasadduq, Imran A.; Otero-Roth, Pablo (IOAP-MDPI, 2022-01-10)We propose an effective, low complexity and multifaceted scheme for peak-to-average power ratio (PAPR) reduction in the orthogonal frequency division multiplexing (OFDM) system for underwater acoustic (UWA) channels. In ... -
Coded-GFDM for Reliable Communication in Underwater Acoustic Channels
Murad, Mohsin; Tasadduq, Imran A.; Otero-Roth, Pablo (IOAP-MPDI, 2022-03-30)The performance of the coded generalized frequency division multiplexing (GFDM) transceiver has been evaluated in a shallow underwater acoustic channel (UAC). Acoustic transmission is the scheme of choice for communication ... -
An energy-efficient integration of a digital modulator and a Class-D amplifier
Zia, M.Y.I.; Tierno, Raúl; Luque-Nieto, Miguel Ángel; Otero-Roth, Pablo (MDPI, 2020-08-16)Energy consumption is always a key feature in devices powered by electric accumulators. The power amplifier is the most energy-demanding module in mobile devices, portable appliances, static transceivers, and even nodes ... -
Energy-Efficient Packet Forwarding Scheme Based on Fuzzy Decision-Making in Underwater Sensor Networks
Pabani, Jitander Kumar; Luque-Nieto, Miguel Ángel; Hyder, Waheeduddin; Otero-Roth, Pablo (MDPI, 2021-06-25)Underwater Wireless Sensor Networks (UWSNs) are subjected to a multitude of real-life challenges. Maintaining adequate power consumption is one of the critical ones, for obvious reasons. This includes proper energy consumption ... -
Multi-Sensor Fusion for Underwater Vehicle Localization by Augmentation of RBF Neural Network and Error-State Kalman Filter
Shaukat, Nabil; Ali, Ahmed; Javed Iqbal, Muhammad; Moinuddin, Muhammad; Otero-Roth, Pablo (IOAP-MPDI, 2021-02-06)The Kalman filter variants extended Kalman filter (EKF) and error-state Kalman filter (ESKF) are widely used in underwater multi-sensor fusion applications for localization and navigation. Since these filters are designed ... -
Optimal Fair Scheduling in S-TDMA Sensor Networks for Monitoring River Plumes
Luque-Nieto, Miguel Ángel; Moreno-Roldán, José Miguel; Poncela-González, Javier; Otero-Roth, Pablo (Hindawi Publishing Corporation, 2016)Underwater wireless sensor networks (UWSNs) are a promising technology to provide oceanographers with environmental data in real time. Suitable network topologies to monitor estuaries are formed by strings coming together ... -
Optimal scheduling and fair servicepolicy for STDMA in underwater networks with acoustic communications
Luque-Nieto, Miguel Ángel; Moreno-Roldán, José-Miguel; Otero-Roth, Pablo; Poncela-González, Javier (MDPI, 2018-02)In this work, a multi-hop string network with a single sink node is analyzed. A periodic optimal scheduling for TDMA operation that considers the characteristic long propagation delay of the underwater acoustic channel is ... -
Self-Organizing and Scalable Routing Protocol (SOSRP) for Underwater Acoustic Sensor Networks
Kumar Hindu, Sateesh; Hyder, Waheeduddin; Luque-Nieto, Miguel Ángel; Otero-Roth, Pablo; Poncela-González, Javier (MDPI, 2019-07-16)Underwater Acoustic Sensor Networks (UASN) have two important limitations: a very aggressive (marine) environment, and the use of acoustic signals. This means that the techniques for terrestrial wireless sensor networks ... -
Underwater Positioning System Based on Drifting Buoys and Acoustic Modems
Otero-Roth, Pablo; Hernández-Romero, Álvaro; Luque-Nieto, Miguel Ángel; Ariza-Quintana, Alfonso (MDPI, 2023-03-23)GNSS (Global Navigation Satellite System) positioning is not available underwater due to the very short range of electromagnetic waves in the sea water medium. In this article a LBL (Long Base Line) acoustic repeater system ...
