Deploying Machine Learning in Baseband and Antenna Processing Algorithms

Abstract

Machine learning has become an incredibly powerful tool for synthesizing and optimizing signal processing algorithms directly from data and simulation across a wide range of vision and voice applications and more recently radio applications. In this talk we highlight key enablers, approaches, techniques and results in the area of multi-element array processing and baseband radio signal processing. We will also highlight recent and ongoing work at DeepSig on improving performance in 5G and other wireless systems through increased density, computational complexity reduction, and enhanced non-linear baseband algorithm design. Finally we will discuss ML driven object recognition and sensing approaching leveraging machine learning on single- and multi- element RF apertures and their ability to provide an unprecedented level of low-latency, broad-band, and highly-sensitive spectral awareness as an enabler to a wide variety of RF sensing and spectrum sharing systems.
