Description
This workshop will demonstrate use of GNU Radio and low-cost SDR hardware such as the Pluto Plus and RTL-SDR to develop and employ multi-antenna techniques to improve signal detection. Examples will include selection diversity, equal-gain combining, maximal ratio combining, and one or more blind adaptive beamforming techniques such as the least-squares constant modulus algorithm (LS-CMA), potentially in combination with time-domain interference cancelation. Development of test harnesses and experimental scenarios for demonstration and performance characterization of these techniques will also be described. Candidate software-based approaches to synchronize low-cost single-channel receivers, such as the RTL-SDRs with 0.5 ppm frequency stability, potentially with sufficient precision to enable the above-mentioned techniques without hardware modification to the receivers, will be presented and their performance characterized using hardware/software test harnesses. Relevant blocks and flow graphs developed by the presenters will be available for download and use under open-source license, e.g., GPL 3 or MIT, to be determined in coordination with the conference organizers.
