It is great to see some simulation results in detail. Too often articles don't give enough background and specifics like this one does. Thanx!

This is a good article and it addresses a thorny problem for SDR design. Getting the RF, modulation, and EC behaviors correct is critical to waveform success. The recent drone capture in Iran actually highlights the importance of this, in my opinion. Noise and jam resistance are critical features of a good waveform. Another area of great interest to SDR designers is the optimization of the waveform at the baseband and networking level. Modern waveforms face daunting requirements in these areas and engineers need tools to assist in ensuring that designs "fit" into the target hardware platfroms. Foresight Systems M&S ( helps engineers optimize the mating of waveform software and hardware. Using our Resource Aware Modeling and Simulation (RAMS) approach, we can predict memory and processor utilization, jitter, latency, etc. enabling engineers to effectively optimize the waveform design.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
