ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada === Many engineers have tried to detect and correct erroneous data in telemetry communications. The best source selector can be used to combine data from two or more bit synchronizers to reduce frame error rates. An error-correcting code can be used as well. These techniques are absolutely helpful to obtain reliable telemetry data. However, some errors still remain and must be removed. This paper introduces the way to effectively merge multiple PCM files that are saved in different receiving sites, and shows nearly errorless data resulting from merging flight test data using a PC-based frame optimizer, which is a developed program.
