Telemetry Frame Generation

摘要

When testing an aircraft, or other vehicle, it is normal to monitor the test on the ground through the use of telemetry. In its raw form, the telemetered data can he thought of as a stream of bits. The mapping of these bits is usually done by defining repeating and periodic telemetry frames. The design of telemetry frames is mathematically difficult (more formally, this problem is known to be NP-Hard). This difficulty can lead to the design of inefficient frames. When that happens, there are many bits being sent that carry no information. Further, there is increasing demand on the spectrum and many ongoing efforts to use this spectrum more efficiently. The algorithm developed during this research project and described in detail in this report will generally produce frames in which more than 80% (and often more than 90%) of the bits transmitted contain information.
