Abstract
The use of trellis coded modulation leads to the requirement of a twofold increase in the channel alphabet size, e.g., from 4-PSK (phase shift keying) to 8-PSK. It is shown that multidimensional 6-PSK trellis codes can be designed which achieve the same spectral efficiency at a reduced channel symbol alphabet size. This allows for easier phase synchronization over 8-PSK. Examples of rotationally invariant as well as noninvariant codes are presented
