Abstract
The Pe-criterion is a recent analysis [1] of sequential BSC channel decoding based on the design condition that decoders may fail with a probability Pe > 0. The result is a definite boundary for the tree search region and a well defined estimate of path numbers searched. This work extends the criterion to the memoryless binary input soft decision channels resulting from the quantization of the AWGN channel output at the receiver, the binary input Q-ary output (Q > 2) and the binary input continuous output (semicontinuous) channels [2]. We show that the use of soft decisions implies a reduced search region compared to the BSC case and that large savings in the number of paths searched may be achieved when soft decision information is available.
