The geometry of the network determines the maximum enhancement achievable, which is demonstrated to be independent from insertion losses. These findings are supported by a mathematical approach, as well as with experimental data.application/pdfeng© 2022 European Microwave Association (EuMA)Beam formingCORPSNetworkNoise factor reductionNoise wave theoryPassiveSignal to noise ratioinfo:eu-repo/semantics/conferenceObject2023-05-30info:eu-repo/semantics/openAccess
