Digitized edition from print [produced by Innovation, Science and Economic Development Canada]. Some pages rotated in this copy. Includes bibliographical references (pages 151-153). v. 1. -- v. 2. "This interim report details progress made in the areas of multipath channel validation, pulse shaping for teletext, and establishing performance of the existing system in typical noise and multipath environments. The existing system employs a truncated 100% raised cosine transmit pulse shape and a conventional teletext decoder. The most important operational characteristics (slicing level estimation and symbol synchronization) of the conventional teletext decoder have been presented in the Telidon System Study 'Second Interim Report'. The first section briefly addresses the pulse shaping problem for teletext. The second section deals with multipath channel validation and the generation of realistic channel characteristics to use for system evaluation. The final section discusses the simulated performance of the existing Telidon system in typical multipath and noise environments. Details have been relegated to appendices for the most part."
