MIMO And Phased-Array Antennas For 5G


Evolving communication systems are driving developments in the RF/microwave industry. The large umbrella of 5G focuses on supporting three main technologies: enhanced mobile broadband, which is the natural development of long-term evolution (LTE), massive machine-type communications, also known as the industrial internet of things (IIoT), and ultra-reliable, low-latency communications providing... » read more

Antenna Array Design for ADAS


By Milton Lien and David Vye By implementing radar technology over the 76 to 81 GHz spectrum, advanced driver-assist systems (ADAS) enable smart vehicles with the ability to alert and assist drivers in a variety of functions, from low tire-pressure warning to collision avoidance to self-parking. These automotive radar applications use the millimeter-wave (mmWave) spectrum to exploit more ban... » read more

5G New Radio Signal Design


By Gent Paparisto, Joel Kirshman, and David Vye The CP-OFDM modulation scheme will have many options. Variable subcarrier spacing (SCS) will be 3.75, 15, 30, 60, 120, 240, 480 kHz with sub-1 GHz of 15 and 30 kHz and sub-6 GHz of 15, 30, and 60 kHz, and above 6 GHz of 60 and 120 kHz. There will be normal and extended CP options. Slot duration will be 0.5 ms, subframe curation will be 1 ms, an... » read more

System-Level Simulation Of Technologies Supporting Enhanced Spectral Efficiency For 5G New Radio


By Gent Paparisto, Joel Kirshman, and David Vye 5G New Radio (5G NR) is the wireless standard defining the next generation of mobile networks. 5G will offer higher capacity than current 4G, enabling a higher density of mobile broadband users and supporting device-to-device and massive-machine communications. 5G research and development will support lower latency, improved reliability, and... » read more

5G Makes Its Public Debut At The Winter Games


We have been spending considerable time and effort with our customers deep in the development of technology that will enable next-generation communications. Work on 5G technology has been underway for several years now-long before the general public will experience its amazing capabilities. So when will this next-generation technology be ready? You'll get a first look next month at the Winte... » read more

Getting Ready For 5G


Evolving communication systems are driving developments in the RF/microwave industry. The big umbrella of 5G focuses on supporting three main technologies: 1. Enhanced mobile broadband, which is the natural development of LTE; 2. Massive machine-type communications, also known as the Industrial Internet of Things (IIoT), and 3.

Software Platforms Bridge The Design/Verification Gap For 5G Communications Design


The integration of simulation technologies, system prototyping tools, and automated test equipment is critical for addressing the complexity of developing 5G wireless technology. In these cases, design teams will need to rely on a combination of simulation and prototype testing in order to ensure design robustness. Although simulation is essential to design a test bed or prototype, measurement... » read more

Software Platforms Bridge The Design/Verification Gap For 5G Communications Design


We are entering the third phase of information connectivity, one that will change the use of wireless technology dramatically. The first phase connected homes and businesses through wired telephony and the early internet via dial-up modems. Over the last few decades, the development of communication networks has been superseded by wireless mobile technology connecting people instead of places. ... » read more
