Abstract
We demonstrate how error propagation may occur with blind sequence estimation based on the Viterbi algorithm (BSE-VA). We further show that differential encoding can be used to alleviate this error propagation in blind sequence estimation. In addition, we compare the BSE-VA with a much simpler differential correlation approach (DCA) method for differentially encoded input symbols
