| Summary: | International Telemetering Conference Proceedings / September 27-29, 1971 / Washington Hilton Hotel, Washington, D.C. === A one-way error correcting system that employs a onethird rate, interleaved, block code was constructed and tested at teleprinter speeds. All system functions including timing and synchronization were tested over a 1300 km VHF ionoscatter path and a 1500 km HF path. The decoder used "minimum-distance decoding." The results showed that coder performance was close to theoretical predictions. A useful secondary output, called the inversion count, was analyzed. A difference in coder performance was noted between the VHF and HF channels. |
