“…Then the corresponding log-likelihood is obtained as The conditional density functions in (16) are Gaussian. As a result, in [1] it is shown that the probability P(Yk IcN) can be expressed, using the Cholesky decomposition of the inverse covariance matrix [10,20] …”

“…Recently, considerable work has been done on trellis-coded PSK signals with differential detection, both for interleaved [14,15] and for uninterleaved systems [9,16,17,18]. In [15] the use of a differential encoder following the interleaver and of a conventional differential detector preceding the deinterleaver is proposed in order to avoid the problem of carrier phase recovery in the receiver.…”

The problem of maximum likelihood (ML) detection of differentially encoded M-PSK signals on Rayleigh fading channels is investigated. It is shown that the solution to this problem can be easily related to previous results [t] and leads to the implementation of a receiver structure based on the Viterbi algorithm and employing per-survivor processing. The error rate performance of this receiver is evaluated by means of computer simulations for both coded and uncoded systems.

“…But differentially encoding trellis-coded symbols changes codewords and thus affects distances, so TCM-DE was commented by "It would be desirable that the performance be directly dependent on the trellis code" [9]. In [12], to further explain this point, we gave an example of two code sequences (1, 1, 1, 1, · · · ) and (−1, −1, 1, 1, · · · ).…”

“…In [9], TCM codes are modified by a form of precoding which combats the effects of the memory due to DE, but the number of encoder states was increased. In [10], NNC TCM without DE was proposed.…”

Differential encoding (DE) is a classical technique at the transmitter that allows simple noncoherent detection at the receiver. On the other hand, trellis-coded modulation (TCM) is a bandwidth efficient technique which offers reliable data transmission. In this paper, we aim to find the best concatenation order of TCM and DE for channel phase coherence over N = 2 symbols. Besides the well-known TCM followed by DE (called TCM-DE), we propose a new trellis coding extension of DE which extends our earlier work, called differential trellis coded modulation (DTCM). DTCM is TCM with DE defined in states where distinct states may have distinct DE functions. We propose design methods of DE functions for noncoherently non-catastrophic DTCM. For both TCM-DE and DTCM, we propose additive distance measures and set partitioning. Based on the proposed set partitioning, trellis codes are designed or searched for both TCM-DE and DTCM. Both minimum distances and simulation results show that TCM-DE outperforms DTCM and the obtained new codes are better than the original codes.
