Here are some examples of bit streams codes with AMI and HDB3. All assume the same starting conditions: the previous 1 bit was −, and the previous violation was an even number of 1 bits ago. (E.g. the preceding bits could have been ++−.)
+1 +1 +1 +1 +1 −1 −1 +1 +1 −1 +1 −1 +1 −22.3 dB Barker codes of length N equal to 11 and 13 are used in direct-sequence spread spectrum and pulse compression radar systems because of their low autocorrelation properties (the sidelobe level of amplitude of the Barker codes is 1/ N that of the peak signal).

Synchronization in communications was a hard problem for Alexander Bain in the development of the teleprinter. [1] Thomas Edison achieved synchronization in his stock ticker with a clunky but effective unison mechanism to resynchronize periodically. [2] In the teleprinter world, Howard Krum finally came up with a good decoding mechanism for ...
The United States Department of Defense's Global Broadcast Service general concept of operations, circa January 2010. Beginning in 1998, GBS began broadcasting via communication payloads on two Ultra High Frequency Follow-On (UFO) Ka-band augmented satellites and more recently all Wideband Global SATCOM (WGS) satellites (via Ka-band only).
The Joint Communications Support Element (Airborne) (JCSE) is a United States Department of Defense (DoD) standing joint force headquarters expeditionary communications provider that can provide rapid deployable, en route, early entry, and scalable command, control, communications, and computer (C4) support to the unified combatant commands, special operations commands, and other agencies as ...
