Abstruct-We present the application and performance of a rate 8/10 Matched-Spectral-Null (MSN) trellis code in conjunction with Class-4 partial response (PR4) signalling. The VLSI implementation of an MSN code is described. Results of experiments using synthesized PR4 waveforms are presented and it is shown that the rate 8/10 code can provide about a 3dB advantage relative to the Class-4 partial response maximum likelihood defection (PRML) in the presence of additive white Gaussian noise as
