Software defined radios (SDRs) are not new. Over 25 years ago, Joseph Mitola introduced the SDR concept in his seminal paper. At the time the paper was published, many communications experts and industry observers anticipated a migration from proprietary, closed architectures to software-defined approaches. After all, software defined implied flexibility, agility, and extensibility—all desirable attributes for communications. However, software in software defined has been the bottleneck to leverage the technology to its full potential. There are various software tools for various hardware targets. Though the FPGAs are being increasingly used in SDR, the learning curve of its programming languages is steep.
 
This white paper will cover:
  • Attributes to consider when designing software defined architectures
  • Elements of software defined architectures:
    • Hardware abstraction
    • Software development environments
    • Technology platforms and processors and FPGAs
    • Advantages and disadvantages

Many quality standards require calibration. This is to reduce measurement risk. But how does calibration reduce measurement risk? How do you know if your calibration provider has been successful at reducing measurement risk? We will explore what is measurement risk and the key drivers of measurement risk. We will explain exactly what calibration is, how it mitigates risk, and the different calibration deliverables. A proper calibration strategy helps ensures end-product compliance and performance is critical for reducing your testing costs. Read our white paper to learn more.

With the race to 5G now underway, the wireless research community has embarked on a journey to create the technologies of tomorrow that will deliver unprecedented improvements in network throughput and capacity, enhancements in spectral efficiency, reduced end-to-end latency, and increased reliability and more. Given the limited availability of spectrum and the projected massive number of IoT devices to come online, one of the key candidate technologies in achieving greater spectral efficiency is Massive MIMO. Using the National Instruments MIMO Prototyping System, researchers at the Universities of Bristol and Lund achieved a record breaking spectral efficiency of 145.6 bits/s/Hz with 128 antennas at the base station and 22 single antenna mobile stations over a 20 MHz radio channel which amounts to a 22x increase in spectral efficiency over today’s existing 4G networks. This white paper describes a flexible MIMO prototyping system that allows you to quickly test on mobility, multi-cell operation, cell edge performance, and other research areas.
