ABSTRACT:
Apparatus is shown for regenerating a signal stream of binary digits which has been distorted by intersymbol interference during passage through a channel (10 and 12) having insufficient channel bandwidth such that the channel output waveform comprises substantially an analog signal. (FIG. 2 at B and D.) After equalization (24) the channel output is converted to a digital sample signal stream at analog-to-digital converter (26). The converter (26) output is supplied to shift register (28) from which successive groups of digital sample signals produced over a plurality of bit intervals of channel output are shifted to decoder (22). Initialization bits that immediately precede the first group of binary digits to be regenerated also are supplied to decoder (22) through sector header reader (20) for use in decoding the first group of digital sample signals supplied to the decoder. During decoding of subsequent groups of digital sample signals, end bits (3,4 and 5) from the preceding group of regenerated binary digits are supplied to the decoder (22). The decoder includes a plurality of trained networks (40-1 through 40-5 and 50-1 through 50-m) of either the neural network or binary tree type.
