ABSTRACT:
A decoder for separating pulse code modulated messages of the type used in ATCRBS where the messages are identified by two framing pulses separated by 20.3 us. and contain information pulses between the framing pulses separated from the framing pulses and from one another by 1.45 us. The decoder receives an input stream of pulses of uniform width from a Leading Edge Detector which has created the stream from video pulses received from the transmitter of another station. The decoder input pulse stream may contain interleaved pulses from more than one message. The decoder includes an input shift register, an analysis shift register, a plurality of buffer storage devices and additional registers to which selected pulses are fed from the input register for use in determining whether a received message is clear of interfering pulses or whether the message is potentially or actually garbled. The input pulse stream is passed through the input register into the analysis register where the framing pulses enable the loading into buffer storage of the information pulses associated with the framing pulses. Pulses in the analysis register at the time a message is loaded into buffer storage and not included in the message loaded may be included in a message later loaded in a second buffer storage device. Means are provided for comparing the messages retained in buffer storage with messages currently being loaded into buffer storage to determine whether garbling exists between the several messages.
