ABSTRACT:
A trellis-coded communications system for encoding a fractional number of bits is described. In this system, the number of allowed state transitions, originating from each state of a trellis encoder, is restricted to a number that is not an integral power of an integer. Furthermore, not all state transitions are used with equal probability.
