Abstract : This document describes analyses performed by the Communications and Control Programs organization to select and optimal (approaching optimum) pulse code modulation frame synchronization code. Existing criteria (e.g., the Inter-Range Instrumentation Group Telemetry Standards) are only partially defining and very complex. This analysis combines these criteria with those of other authors and drives an optimal 28-bit code. Simplified criteria were established and a new technique of code selection was developed for any code length. This technique greatly expedites the selection of an optimal code.
