We consider the design of convolutionally coded systems and low-complexity receivers for communicating through inter-symbol interference (ISI) channels when iterative equalization and decoding is employed in the receiver. We first introduce a binary precoding technique that makes a non-recursive ISI channel `appear' recursive to the outer code and, hence, provides excellent bit error rate (BER) performance. Then, a low complexity soft output algorithm based on the M and T- algorithms is proposed for soft-output equalization of channels with long memory.
