On coded and multi-dimensional partial response signaling

In English Optimal finite partial response signals based on 2 and 4 PAM have been found by Said and Anderson. The encoder is a simple discrete-time filter, whose combination of bandwidth and Euclidian distance is optimized. Here we extended the idea to the case where the modulated symbols are first encoded by a short convolutional encoder. This gives power gains of 1-3 dB while maintaining the same
bandwidth. We also investigate possible gains from multi dimensional partial response signaling.
