Deepwave’s AIR-T for CBRS Radar Sensor

Deepwave's AIR-T Shows Viability as CBRS Sensor

Deepwave Digital is proud to announce that their sensor has concluded certification testing to become a critical component in the 5G Citizens Broadband Radio Service (CBRS) network: the first commercial spectrum sharing network. The Deepwave team has implemented a deep neural network on their Artificial Intelligence Radio Transceiver (AIR-T) that is capable of detecting, classifying, and reporting the presence of naval radars with extreme accuracy.

Today, Deepwave Digital's partner Key Bridge Wireless announced the conclusion of their Environmental Sensing Capability for the Citizens Broadband Radio Service (CBRS) in a press release. “We have leveraged the latest methods in AI and deep learning to create a sensor that correctly identified every radar signal variant in the certification test suite with extremely high accuracy,” said John Ferguson, CEO of Deepwave Digital. ”Our detection algorithm was trained on tens of thousands of radar variants spanning the entire parameter space. We have coupled this software with our embedded, NVIDIA GPU-based software defined radio. This allowed us to demonstrate that AI is a commercially viable solution to detect and discern current and future incumbent radar waveforms.”

CBRS Overview

Historically, spectral bands have been assigned for specific applications. The CBRS network changes this paradigm by allowing the 3.5 GHz band to be utilized for both naval radars and commercial services such as LTE. A critical component in the CBRS network is the Environmental Sensing Capability (ESC) sensor. This sensor provides the ability to detect and discern the Navy user. If it does not detect a Navy user, the downstream network will provide access to the 3.5 GHz band for commercial services such as LTE. If the ESC does detect a Navy user, the band will not be available to commercial services.

Deepwave’s Presentation at GTC DC 2019

End-to-End Signal Processing and Deep Learning Using Embedded GPUs

The following presentation was given at NVIDIA's GPU Technology Conference (GTC) in Washington, DC on November 5, 2019. It was a great event where technology was showcased from many different research areas.

We’ll present the GPU-accelerated digital signal processing (DSP) applications enabled by Deepwave Digital’s AI Radio Transceiver (AIR-T). We’ll also discuss our open source development tools and performance benchmarks for this new type of software-defined radio (SDR). By coupling NVIDIA’s TensorRT toolkit with the AIR-T, clients can rapidly develop and deploy deep learning applications at the edge of wireless systems. We’ll walk through a workflow for deep learning in wireless applications, including the acquisition of training data with the AIR-T, model training and optimization, and live inference on the AIR-T. Our solution addresses the issue of SDR bottlenecks. Because many DSP algorithms are highly parallelizable, GPUs can increase the throughput while maintaining simplistic programmability. With the new shared memory architecture of the NVIDIA Jetson products, GPUs are now a viable solution for optimizing short development times and high data rates while minimizing latency.
