There are so many great open source libraries and tools that people have written that make up the software defined radio ecosystem, but we have unfortunately created a high bar for consumption of this software, and an even higher bar for using modern versions. In this presentation we look at how we can use modern C/C package management with Conan to simplify the lives of our users who want to use the latest versions without living in dependency hell.

We examine the use of equalizers in wireless communication systems, how these are implemented in GNU Radio, and how the existing GR equalizer functionality can be extended with a new OOT using training-based adaptation. The theory of multipath channels, ISI, and how to overcome with adaptive equalization will be reviewed and shown with interactive flowgraphs. Please note that this talk was originally scheduled to be given at 2:30 PM and will now take place at 10:00 AM.

GNU Radio is the widest used software radio stack for research and development on PC-style hardware, having enabled hundreds of high-rate applications. I'll discuss where its limits are, where we need to stick to GNU Radio's recipe for SDR success, and where to disruptively address its architectural shortcomings

Abstract: Radio based communication systems and imagers operate under real-time constraints. Off-loading computes to an FPGA seems like a solution to speeding-up your application but comes with many pitfalls. Specifically, software-oriented implementations fail to achieve the required interface bandwidths or computational throughput required to see a speed-up. In this talk, we will discuss the organization of common compute motif's in software-defined-radio and their complexity in time and ...

gr-satellites is a GNU Radio out-of-tree module with the goal of decoding every Amateur satellite. Currently it supports more than 80 different satellites. After GNU Radio 3.8 was released last summer, gr-satellites is seeing a lot of development and important changes. A refactored version, which will be released as gr-satellites 3.0 is on the works. This version brings more modularity to avoid code duplication, more flexibility in the input and output that the user can employ, and the idea to ...

Combining the flexibility of FPGA hardware configuration with the high abstraction level of an operating system running on a general purpose central processing unit (CPU) requires mastering a broad range of knowledge, from low level hardware configuration to kernel drivers to libraries and userspace application. While some vendor specific frameworks tackle the challenge, we focus on a vendor independent solution applicable to current FPGA Systen on Chip providers: the OscImp Digital framework ...
