The objective of the program is the development of a device to lower the bit error rate of a troposcatter channel by correcting errors which occur between the transmission and reception of the digital signal. The decoder is capable of accepting 1 an analog signal from which a three-bit parallel soft decision eight-level quantization can be made or, 2 a one-bit hard decision type signal. The interleaverdeinterleaver concept is to be employed to enhance system performance during periods of signal fading while in the hard decision mode of operation.
