“…Usually, data collected from the sensors is weak with many other problems like serious noise, so the signal conditioning circuit is needed to complete the tasks of signal bridging or matching, and to realize the protection of the circuit and signal shaping, amplifying 12 and other functions.…”

Signal acquisition system is widely used in various fields of reality, due to the data acquisition rate and processor performance enhancement as well as the development of sensor arrays and other technologies, the data acquisition system acquisition and transmission of the signal is exponential growth, in order to solve the high-speed signal acquisition process of the large amount of data, real-time, transmission rate and other issues, the study of high-speed acquisition of signals as well as the transmission program has an important practical significance. FPGA is very suitable to be applied in high-speed signal acquisition system because of its characteristics. In this paper, we firstly introduce the composition of a typical highspeed signal acquisition system based on FPGA, and then briefly introduce the function and development process of each module of the system and introduce the mainstream programs used in several key modules. In engineering applications, different programs should be used in different modules in conjunction with the actual.

“…In terms of traffic safety applications, vehicle location information and its surrounding data are essential either for driving-assisting systems or autonomous vehicles. The existing tools for location determination in the latest autonomous cars are global positioning systems (GPS) [321], radar [322,323], and lidar [324]. Even though these methods gained popularity, a GPS gives poor performance due to link and multipath blockage, particularly inside tunnels or underground; radar has high cost and severe RF interferences; and lidar has a low scanning rate and high cost.…”

This review paper discusses the complete evolution of free-space optical (FSO) communication, also known as unguided optical communication (UOC) technologies, all the way back to ancient man’s fire to today’s machine-learning-supported UOC systems. The principles, significance, and developments that have happened over the past several decades, as well as installation methodologies, technological limitations, and today’s challenges of UOCs are presented. All the subsets of UOC: FSO communication, underwater optical wireless communication (UOWC), and visible light communication (VLC), with their technology/system developments, potential applications, and limitations are reviewed. The state-of-the-art developments/achievements in (i) FSO channel effects and their mitigation techniques; (ii) radio-over-FSO techniques; (iii) wavelength division multiplexing and sub-carrier multiplexing techniques; (iv) FSO for worldwide interoperability for microwave access applications; (v) space optical satellite communication (SOSC); (vi) UWOC; (vii) photoacoustic communication (PAC); (viii) light-fidelity; (ix) VLC; (x) vehicular VLC (V2LC); and (xi) optical camera communication are reviewed. In addition, the current developments on emerging technologies such as artificial intelligence (to improve the performance of UOC systems), energy harvesting (for the effective utilization of UOC channels), and near-future communication network scenarios (mandatory for secured broadband digital links) are covered. Finally, in brief, to achieve the full potential of UOC systems, challenges that require immediate research attention are summarized.

Frequency-modulated Continuous-wave (FMCW) radar is a powerful sensing technology. It is widely used in various applications. This paper presents an in-depth exploration of the FMCW radar signal generation using Direct Digital Synthesis (DDS) technology. DDS offers precise and flexible control over the frequency modulation required for FMCW radar systems. The fundamental principles of FMCW radar were delved into in this study, with emphasis placed on the importance of continuous frequency modulation in achieving accurate range and velocity measurements. We discuss the essential components of an FMCW radar system, focusing on the critical role played by DDS in generating the required frequency-modulated signal.
