Our #ESR Alejandro Antón Ruiz presented his paper Impact of Excitation and Weighting Errors on Performance of Compact #OTA Testing Systems at eucap euraap. In his work, he explores the impact of complex excitation errors of a chamber array antenna on the accuracy of the test zone of a random line-of-sight over-the-air testing setup. Several combinations of compact chamber arrays of different lengths and distances emulating a plane wave impinging at the test zone were obtained. The similarity of the obtained field distribution to that of a plane wave was assessed. Moreover, the performances of the matched filter and zero-forcing (ZF) algorithms were evaluated for DuT’s array weighting coefficient errors showing that the errors were more significant at higher SNRs and the ZF was more sensitive to errors. Excellent work Alejandro Antón Ruiz!!!
