To analyze the transmission characteristics of the proposed system, we designed a prototype modulator and demodulator, and measured their performance through laboratory experiments. Further, we also evaluated the proposed system via large-scale field trials under conditions similar to actual broadcast propagation environments. This paper presents the concept and specifications of the proposed system. The verification results of a computer simulation, and laboratory and large-scale field experiments are also described.", "abstract$meta": { "confidence": "high", "note": "Ingested from SMPTE IDAMS (_source/SMPTE/Journal Article Repository/2020/7261654/9136808/09136826.xml) via idamsIngest.js", "source": "parsed", "updated": "2026-10-07T17:09:33.718Z", "version": "smpte-idams-publication@v1" }, "authors": [ { "bio": "Noriyuki Shirai received BE and ME degrees in electrical engineering from the Tokyo University of Science, Chiba, Japan.
