John, I think this is what you're looking for: http://www.fcc.gov/Bureaus/Engineering_Technology/Reports/oetrpt4901.doc In case the URL gets messed up, the document is OET document TRB-00-1. Here's an exerpt from the executive summary: "In the interim since COFDM was first analyzed in the US, COFDM was chosen as the European broadcast digital transmission system, i.e. Digital Broadcast Television - Terrestrial or DVB-T, under a somewhat different broadcast television system architecture, and has benefited from substantial investment in development. In the rush to get 8-VSB consumer receivers to market in the US, the first generation of receivers sold were implemented with channel equalizer technology in a relatively early stage of development. In the two years since the first receivers were offered for sale, manufacturers have introduced sets incorporating second-generation technologies, and have developed prototype receivers using integrated circuit chip sets with what now can be considered third-generation technologies. "The Commission was petitioned to allow COFDM as an alternative to 8-VSB, with proponents of this position offering field demonstrations purporting to show the relative superiority of COFDM in difficult reception conditions and emphasizing anecdotal failures of early 8-VSB consumer receivers.1 This controversy has, however, spurred the continued development of the 8-VSB receivers, particularly the channel equalizers, and also focused the attention of the Commission on the need for an objective and scientific analysis of the state of 8-VSB receiver performance." There might be more studies from the FCC, but that's the quickest one I could find, and I remember reading it when it first came out. What they said way back then turned out to be true. About one year after this was written, Linx demoed their 4th gen technology, which was easily better than the 3rd gen receivers mentioned in this report. Although as we all know, that doesn't mean the good stuff is on the store shelves yet.
