Inspecting GNU radio applications with controlport and performance counters
Thomas W. Rondeau, Timothy J. O’Shea, Nathan Goergen · 2013
Due to differences in the operating system and the effects of sample rate on the computational load of a software radio, we have historically had a difficult time understanding the performance boundaries of software radio applications. This problem further leads to difficulties in debugging, optimization, and profiling analysis of both software radio frameworks and applications.
