“…The signal modulated by OFDMA is transmitted by the transmitter and received after transmission in the wireless channel. The receiver redivides the OFDMA data into data of multiple subcarriers through FFT operation [17], and estimates the channel according to the known data (pilot) inserted at the transmitting end. Finally, all the transmitted data are inversely derived according to the results of channel estimation.…”

As 5G small cells gradually become the main force of 5G indoor deployment, it is necessary to study channel estimators for 5G small base stations, but there has been limited research on high-performance channel estimators in recent years. This study implemented a low-delay, low-overhead, relatively universal channel estimation module by dedicated instruction set acceleration including reference signal estimation, Wiener, 1st order, and 2nd order interpolations in frequency and time domains. The instruction level acceleration is on our vector processor, yet is suitable for other commercial and academic vector processors. Through instruction acceleration, compared with the existing general vector processing instruction sets, the processor performance of the LS estimation module and Wiener filter interpolation in the frequency domain is improved by 50% and 37.5%, respectively. The BER VS SNR measure of time–frequency Wiener filter interpolation achieves 4 db compared with linear interpolation, meaning our instruction level acceleration can be an optimum solution.

“…Composite material structures have attracted interest for various industrial applications based on their ability to improve their strength-to-weight proportion when analyzed with non-reinforced materials [1]. Digitalization will encompass the majority of engineering fields, with a bigger impact over wide-area communication networks involving fast data transmission [2][3][4]. A significant amount of research has been expended and recounted over various reviews in the field of machining composites [5][6][7].…”

Ceramic matrix composites (CMCs) have grown in popularity as a material for a range of high as well as protection components, increasing the need to better understand the impacts of multiple machining methods. It is primarily composed of ceramic fibers embedded in the matrix. Ceramic materials, especially carbon fibers and carbon were used to create the matrix and fibers. These ceramics include a huge variety of non-metallic inorganic materials that are regularly utilized under high temperatures. The aircraft industry became revolutionized by this unique combination of materials, which made parts better resistant under extreme conditions as well as lighter than the earlier technology. The development, properties, and production of ceramic matrix composites, as well as space applications, are discussed in this article. Ceramic materials have an interesting set of properties, including great strength and stiffness under extremely high temperatures, chemical inertness, low density, etc. In CMC, ceramics are used in the matrix as well as reinforcement. The matrix material keeps things running smoothly while the reinforcement delivers unique special properties. Ceramic matrix composites are developed for applications that required high thermal and mechanical characteristics, which include nuclear power plants, aircraft, chemical plants, space structures, and transportation services. Even though advanced aircraft relies on high-performance propulsion systems, improving the total impulses over the total mass ratio for rocket engines becomes essential for improving their performance that demands reduced engine structural weight as well as higher component heat resistance. The evolution of new ultra-high-temperature composites having high-temperature resistance as well as low density that a substitute super alloy and refractory metal material has become so essential and laid the foundation for high-performance engine design. The benefits of continuous fiber- reinforced CMC with high-temperature engine designs have long been recognized as a better measure of a country’s ability to design and produce spacecraft, modern aircraft, and weapons. Ceramic matrix composites materials are used in various aircraft type engines, aircraft brake disks, high-temperature gas turbines components, slide bearing components, hot gas duct, flame holders and components for burners are made by using oxide CMCs.

Polymer matrix composites (PMCs) may be found in nearly every facet of modern society, from electronic components to a broad range of accessories. Polymer matrix composites contain materials that include a matrix polymer. It is also made up of multiple continuous and short fibres that are held together in the organic polymer matrix. In this article, the development, properties, and production of polymer matrix composites along with electronics applications were discussed. The matrices in recent developments of polymer matrix composites have been made of thermosets or thermoplastic materials. The properties of a PMC such as a matrix and reinforcement offer great strength and rigidity, and it is largely employed to increase fracture toughness. The process of manufacturing composites has a significant impact on the product design and outcome. The ability to make a product from a variety of manufacturing techniques is unique to the composites industry. Polymer-based materials were employed in a variety of applications, including the automobile industry, aircraft industry, marine, sports good equipment, electronics applications, and biomedical applications. The great potential of filler reinforced polymer composites used for microelectronic applications. Woven glass fibre cloths and reinforcing materials such as paper, glass fibre matte, and fillers are used to fabricate printed circuit boards. Thermoplastics and thermosets are used in electronic packaging material which increases efficiency and offers more stringent requirements. Polymer composites have good thermal conductivity and desirable dielectric properties which improves microelectronic performances. Nanocomposites are composites in which nanofillers were distributed inside a polymer. The compatibility and interface between the filler and matrix play a significant effect in modifying overall characteristics in polymer nanocomposites.
