Evaluation of a GNURadio-based multi-channel ADS-B receiver implemented on a highly integrated SDR platform for space application

This paper presents a multi-channel Automatic Dependent Surveillance-Broadcast (ADS-B) receiver approach based on a GNURadio implementation on a highly integrated software-defined radio (SDR) platform for space application. The receiver is implemented to run standalone on the embedded platform and to receive on up to four channels simultaneously. The presented test results show the general feasibility but also uncover the bottleneck of GNURadio-based implementations on embedded SDRs and its issues with respect to real-time constraints.
