Abstract
The author describes a method of combining trellis-coded (or coset-coded) modulation concepts with those from the design of run-length limited coding. The method is referred to as the trellis-constrained, run-length code approach. It is shown that this approach, which introduces redundancy in the transition sequence, provides improved noise immunity and can be used in recording systems to increase the data density while maintaining data integrity, without increasing the density of transition
