Error-control properties of minimum shift keying

A phase representation of minimum shift keying (MSK), which is a general framework suitable for use with other continuous phase modulation (CPM) schemes, is discussed. The representation is used to show that MSK can be viewed as a coded-modulation scheme with an expanded signal set using Ungerboeck's set partitioning concept (see IEEE Trans. Inf. Theory, vol.IT-28, no.1, p.55-67, 1982). The properties which follow from this view of MSK are explored. The uniqueness of the representation of MSK as a coded-modulation scheme and the structural relationships between different versions of MSK are described.<
