Thus, the received signal vector xk∈CN×1 at the UAV can be expressed as(11)xk=P1,khksk+∑j=1,j≠kKP1,jhjsj+n1where n1 denotes the Additive White Gaussian Noise (AWGN) with mean zero and variance σ12. Then, after implementing receive beamforming with wr∈CN×1 at the UAV, the ...
analyzing radio frequency interference (RFI) with a focus on how it affects satellite ground stations and radio telescopes. We note that in the pastwe've postedseveral times about Apostolos' other project called PICTOR, which is an open source radio telescope platform that makes use of RTL-SDR...
