Meeting the Challenges of RF with mmWave for 5G

Tuesday, 30 October 2018 - 2:00 PM EDT

Millimeter wave (mmWave) frequencies in combination with small Radio Frequency (RF) coverage look to be key technologies for 5G networks. However, mmWave spectrum comes with high path losses and the solution of small RF coverage to reduce signal congestion suffers from distortions of the transmitted signals. This webinar will look at how measurements of RF front ends designed for mmWave can help address whether commercial-off-the-shelf chip-based RF front end technology is ready to be used for 5G networks.

Smart Signal  Processing for Massive MIMO in 5G and Beyond

Monday, 24 September 2018 - 2:00 PM EDT

In less than a decade, Massive MIMO has gone from being a futuristic concept to a key technology in 5G, and an elementary form of Massive MIMO has even made it into LTE networks this year. With the advent of Massive MIMO, we can finally exploit the spatial domain for more efficient communications and multiplexing of users. Massive MIMO is a theoretically very powerful technology, but with great power comes great responsibility for the engineers that implement the system. The signal processing used for channel estimation, multiuser detection in the uplink, and precoding in the downlink must be implemented in the right way, otherwise, we will only achieve a small fraction of the theoretical capacity gains. Simplistic algorithms such as matched filtering and eigenbeamforming have received a disproportionate attention from the research community, probably because they are easy to analyze and implement. Moreover, the seemingly smart zero-forcing algorithm that works well in single-cell scenarios has been commonly applied in multi-cell scenarios, which it is not designed for.

In this webinar, the basics of Massive MIMO will be explained and what characterizes a smart signal processing design. This includes the concept of MMSE processing and how the spatial channel correlation ought to be utilized for interference suppression in practical multi-cell scenarios. The webinar culminates in the definition of Massive MIMO 2.0, which hopefully will be implemented in future releases of 5G.

MIMO Radar and Its Role in Autonomous Driving

Tuesday, 24 July 2018 - 3:00 PM EDT

Radar not only has found widespread application in advanced driver assistance systems (ADAS) but also is one of the key technologies to enable environmental perception in autonomous driving. Unlike the traditional phased-array radar system that transmits via its antenna array a single waveform with different phase shift, multiple-input multiple-output (MIMO) radar can transmit multiple waveforms that may be chosen freely. As compared to traditional radar system with the same number of transmit and receive antennas, MIMO radar achieves significantly improved spatial resolution by exploiting waveform diversity. Due to its advantages, MIMO radar technology has been widely used in designing millimeter-wave radar sensors for ADAS and self-driving cars.

This webinar will look at the fundamentals of MIMO radar as well as novel MIMO radar approaches with the emerging sparse sensing techniques. It will also focus on the role of radar in autonomous driving and various aspects of automotive radar signal processing techniques.

How Radar and Wireless Systems Coexist: An Analysis From Spectrum Sharing to New Regulations

Thursday, 21 June 2018 - 2:00 PM EST

As wireless communications have become ever more important, access to wireless spectrum has become increasingly difficult. The so-called “spectrum crunch” describes a situation in which there is not enough spectrum available to support all of the networks and devices desired. As a result, a critical capability of wireless devices is the ability to share the spectrum they use with other devices, be they communications devices or not. For example, one class of critical spectrum user is the radar system for weather forecasting, navigation, and defense.

This ability to share spectrum with other users has both regulatory and non-regulatory aspects. From a regulatory perspective, there are rules designating how a wireless system needs to behave in order to protect critical operations, or fairly share the spectrum with other users. Beyond regulation, however, there is freedom of operation, and some devices will make better choices in the presence of wireless interference than will others. Network operators need a way to test the performance of devices in the presence of interference, both to understand their ability to support regulatory requirements, and to understand what kinds of choices they are designed to make.

We will provide an overview of the spectrum sharing landscape, including DFS/radar requirements, new regulatory regimes such as CBRS in the US, and industry-driven activities such as the cellular/Wi-Fi co-existence test plan for LTE-U. In addition, we will discuss how devices that operate under these various conditions can be tested to understand their performance.

Designing Energy Efficient 5G Networks: When Massive Meets Small

Wednesday, 20 June 2018 - 2:00 PM EST

The global mobile data traffic is growing at an exponential pace. 5G is supposed to handle 100-1000 times higher throughput than current networks, but this comes at the price of a much higher energy consumption and cost, unless we can make future networks radically more energy efficient. As a first step, we need to make the energy consumption load adaptive, to save power when the data traffic is low. As a second step, we need to design the network architecture with energy efficiency in mind. In this webinar, different strategies for designing energy-efficient 5G networks will be discussed and compared. By taking a holistic approach, we will see how a mix of Massive MIMO and small cells is the most attractive solution. The speaker received the 2018 IEEE Marconi Prize Paper Award in Wireless Communications for his work on this topic.

Moving From Testing the Internet of Thing Towards the Internet of Tested Things

Originally broadcasted on Tuesday, 16 January 2018 

The term “5G” is applied to a broad range of applications, from mobile broadband to fixed access.  But foremost among the drivers for 5G is the desire to use mm-wave technology to support the Internet of Things (IoT), including the growing area of M2M (machine-to-machine) communications.  From the IoT, we get the requirement to be able to support 10-100x the number of devices supported by today’s networks, which leads to the question, “who is going to create all these devices?”  In this presentation, we explore the implications of a dramatic increase in the number of wireless device developers on product testing and discuss how increased access to testing equipment can help to smooth the path to the 5G future.

Addressing Direction Finding in Over-the-Air Testbeds and Prototypes

Originally broadcasted on Tuesday, 19 September 2017

Direction finding has found use in many applications that include military or security, spectrum monitoring, geo-location and intelligent communications like SDMA. It is an indispensable first step in most radio-detection systems. Multi-antenna systems make direction finding easier and reliable. As the source signal reaches an antenna array, one can take advantage of the variations in the received signal at each antenna, together with the knowledge of the array characteristics, to determine the direction of arrival of the signal. This approach requires the antennas to be calibrated and synchronized, and achieving this, is a challenge. This Webinar provides an overview of the practices and methodologies employed in direction finding particularly for communication systems, highlighting their advantages and drawbacks. An overview of a 128-antenna massive MIMO testbed will also be given to provide an example of how practical direction-finding research could be conducted.
