Abstract
A partial response (PR) equalization technique for an FM recording code is proposed. First, the noise power spectrum and the eye patterns at the discrimination point for the PR system are compared with those for Veillard´s system. Then, the bit-error rates of bit-by-bit decoding and Viterbi coding for these systems are obtained by computer simulation. The results show that the PR system has improved performance, both for bit-by-bit decoding and for Viterbi decoding, over Veillard´s system
