Abstract: The journey of a developer in the realm of software-defined radio (SDR) often commences with the utilization of commercial off-the-shelf (COTS) SDR modules. These modules are pivotal for initial proof of concept and the development of algorithms, where the decision to make or buy is a straightforward one. However, for some, this journey extends beyond the preliminary phase,...
