Abstract :
Optimal finite partial response signals based on 2 and 4 PAM were found by Said and Anderson. The encoder is a simple discrete-time filter, whose combination of bandwidth and Euclidian distance is optimized. Here we extend the idea to the case when the modulated symbols are first encoded by a convolutional encoder. Good narrowband codes are the result.
