“…In this implementation, Golay sequences are employed as the pulse compression sequence. The Golay sequence contains a pair of subsequences Ga and Gb [12]. One unique property of the Golay sequence is that the summary of the cross-correlation of the two subsequences will have the sidelobes canceled out, which is highly desirable in any pulse compression scheme.…”

For the last decade, Harbor Branch Oceanographic Institute at Florida Atlantic University (HBOI) has been developing Integrated Multi-Trophic Aquaculture (IMTA), where multiple species are farmed together. Compared with the traditional Recirculating Aquaculture Systems (RAS), the IMTA system can improve efficiency, reduce waste, and provide ecosystem services. For the IMTA system to be successful at a commercial farm scale, HBOI is developing an AI-centric Internet of Things framework to support the operations of the IMTA system. The Pseudorandom Encoded Light for Evaluating Biomass (PEEB) sensor is an endeavor in this effort to realize automated monitoring of the growth of the Sea Lettuce (Ulva lactuca), an important organism in the HBOI IMTA system. PEEB utilizes the measurements from a sequence of encoded light flashes to quantify the seaweed biomass. Such a configuration ensures the sensor can operate under different ambient light conditions and biomass densities. An improved PEEB sensor based on a unified electronic sensor design that is more robust against ambient conditions and capable of long-range data transmission is discussed. This electronic design will be the backbone to support future sensors for the IMTA system. Multiple PEEB sensors have been deployed at the HBOI IMTA system. The cloud-based storage and analysis of the sensor data are discussed.

“…To enhance the performance of the correlator we adopt the Golay waveform known for its high mainlobe to sidelobe ratio [23], [24]. The sidelobe cancellation property of these waveforms provides a substantial improvement over the generic minimum PSL code utilized in Section II.…”

This work presents a phase-modulated radar based on an analog correlator. We demonstrate a novel radar architecture that combines the energy efficiency of analog processing and the accuracy and flexibility of digital processing while avoiding their respective pitfalls. We introduce the proposed analog correlator, describe its theory of operation, and develop a numerical model to analyze and predict the output and the detection sensitivity. Next, we perform a thorough architectural analysis and present system-level simulations of the proposed structure. Finally, based on this investigation we derive circuit requirements and perform extensive radar simulations characterizing the performance of the implemented analog correlator. There is agreement between theoretical derivations, expected performance from system-level models, and the resulting performance from circuit-level time-domain simulations, demonstrating the feasibility of the proposed scheme for high-performance pulse-modulated radars.

“…As for the modulation scheme, 𝜋/2 -shift binary phase-shift keying (BPSK) with spreading was employed. Spreading is performed by multiplying a Golay sequence [22,50] with a spreading factor of 64 to make it compatible with the preamble sequence, which also uses a Golay sequence for frame synchronization [51,52] and channel estimation [53]. As a coding scheme, the Reed-Solomon code [54] was applied, considering the hardware complexity at the time of the standardization activity.…”

With advancements in distributed autonomous systems (e.g., vehicles, sensors, and robots) in the 5G/6G era, sidelink communication technology has evolved as a distributed communication system in the third generation partnership project (3GPP). However, the current low-rate point-to-point sidelink communication design is not suitable for rapid development of such autonomous systems. Instead, based on sidelink, developing distributed wireless personal area networks (WPANs) with a drastically higher rate are essential. The overarching goal of this study is to explore the possibility of sidelink communication evolution to 1) form a distributed and autonomous WPAN and 2) support millimeter wave (mmWave) bands. Our core idea is to merge several design concepts of the precedented mmWave WPAN standards, i.e., IEEE 802.15.3c/11ad, into the sidelink communications, thereby bridging the gap between the two separated systems. This paper presents the anatomy of the IEEE 802.15.3c/11ad system with a focus on the formation of mmWave WPANs among distributed nodes and their operation. In addition, the current status of sidelink communication system design is highlighted, along with the missing building blocks, which are required to develop 3GPP sidelink-based mmWave WPAN systems. Simulation results on network formation signaling in the mmWave WPANs shed light on merging IEEE 802.15.3c/11ad concepts into 3GPP sidelink communication.
