minimum error probability performance on the Rician fading channel (see ibid., vol. 36, no.
9, p. 1004-1012, Sep. 1988) is extended. It is demonstrated that allowing for multiple
symbols per trellis branch, ie, multiple trellis-coded modulation (MTCM), provides an
additional degree of freedom for designing a code to meet the optimization on the fading
channel. Diversities larger than those achievable with conventional trellis codes having the …
