    Development Of The Next-Generation Openvpx-Based Embedded System Standard

    Something exciting is happening in the service representative community. Representatives from three different programs, one from each of the U.S. Department of Defense (DoD) services, have come together with a common objective to solve their respective acquisition problems with an agreed upon, open architecture standard. Here is the final part of a 3-part article covering the SOSA (Sensor Open System Architecture) Consortium’s efforts.

Introduction to ANSYS® 5G Antenna Solutions

5G promises a spectacular world of wireless communications systems. It presents lucrative opportunities in consumer electronics, internet-of-things (IoT), advanced driver assistance systems (ADAS), telecommunications, entertainment, medical, transportation and other sectors. This white paper addresses the complexity of designing various points in these kinds of systems, and discusses how ANSYS products are a possible solution to design and simulate antenna systems, antenna-to-antenna coupling, environmental effects on signal propagation as well as V2V and V2X communication for traditional and autonomous vehicles.

Introduction Into Theory Of Direction Finding

While direction finding for navigation purposes is becoming less important, there is a growing demand for determining the location of emitters as the mobility of communications equipment increases. The importance of direction finding lies in the fact that spread-spectrum techniques are increasingly used for wireless communications. This means that the spectral components can only be allocated to a specific emitter if the direction is known. Direction finding is therefore an indispensable first step in radio-detection, particularly since reading the contents of such emissions is usually impossible.

Functionality Testing Of Automotive Infotainment Devices

Modern day vehicle interactivity takes place on the centrally placed touchscreen head unit display (HUD) on the car dashboard and their infotainment systems have become a central hub for a wide range of vehicular functionality. These systems provide driver entertainment and information by integrating different functions. Examples include in-vehicle connectivity with wireless devices and connecting with external communications, transmission, radio and satellite network providers. This article discusses the challenges of functionality testing in automotive infotainment devices and presents a test and measurement solution.

The Wi-Fi Evolution

If you are looking to buy a new wireless networking gear or a mobile device, you may be overwhelmed by too many choices and abbreviations. Since Wi-Fi was first released to consumers in 1997, its standards have been continually evolving – typically resulting in faster speeds and network/spectrum efficiency – and it can be difficult to keep track of new standards. This paper is meant to help you understand the basics of Wi-Fi standards, and provides and overview of the evolution of Wi-Fi technologies.

    Antenna Design and Integration into Mobile Devices

    FEKO, Altair’s comprehensive electromagnetic simulation software suite, can be used in electronic virtual prototyping and simulation driven designs, including antenna design for many products such as mobile phones, tablets, cameras, laptops, and TVs. The software can eliminate weak antenna designs and reduce the number of prototypes with its proof of concept and comparative studies. Pre-compliance of over-the-air (OTA) radiation performance and specific absorption rate (SAR) can be estimated for the standalone device, or for different usage environments.

    What Is Your Old Spectrum Analyzer Hiding From You?

    Digital Phosphorus Technology, or DPX, is a Tektronix patented acquisition mode that performs the hardware DSP processing and rasterizing of the samples into pixel information in order to reveal a greater amount of signal detail. It gives a truly “live” view of the RF signals, with its color-grading feature allowing users to see different signals at the same frequency yet separated by either time or power levels. In this video, DPX is demonstrated and reveals signals that your old spectrum analyzer might be hiding from you. You can literally see signals hidden beneath other signals!
