AbstractFrame synchronization of PCM telemetry data can be accomplished very effectively by employing the fixed threshold method with a unique strategy. Probability of false sync acquisition and maintenance can be made negligibly small for data having bit error rates less than 10%, at a small sacrifice in acquisition time. Furthermore, experimental results indicate that frame synchronization is significantly affected by the frame sync code length rather than by the code pattern itself, i.e., any pseudo-random code is just as good. The difference in performance between "optimum" codes and any pseudo-random code is negligible.
