Explanation

Burst error protection

The ability to achieve a reasonable

error rate in an environment where

burst noise is present either in

the form of jamming or natural

phenomena.

De-interleaving

The reverse process of interleaving.

Has the effect of breaking up blocks

of errors introduced into the

interleaved data stream.

Forward error correcting

The ability to correct errors in a

transmission without retransmitting

the data

Interleaving

The process of shuffling a serial

data stream in time before trans-

mission. This process allows

blocks of errors to be scattered

in time by de-interleaving on the

receive side.

Equipment Characteristics, Capabilities and Features

The decoder is a forward-error-correcting decoder which means that the decoder corrects errors without using a return

communication link. Encoding and decoding functions are independent so that the-encoder decoder provides a full duplex

digital communications capability. The encoder-decoder has built-in test equipment for on-line and off-line self-tests which

isolate to the circuit card assembly. The encoder-decoder also generates a-test signal which may be used to check the

communication channel from end-to-end.
