“…In [3], a NB-TC structure was derived from a protograph subensemble of a NB-LDPC code. In [10], NB-TCs over GF(q) were designed based on their EXIT charts and an estimate of their truncated union bounds (TUB). Both studies report significant gains in the short-to-moderate block size regime compared to state-of-the-art binary FEC codes.…”

“…When the cardinality of the code alphabet q is high, a large number of transitions connect the states in the code trellis, making the enumeration of the sequences very complex. In [10], the M-algorithm is proposed to calculate TUBs for NB convolutional codes (NB-CC): only M branches, having the least reliable metrics, are considered at each trellis section. The union bound analysis is then only used to select the constituent convolutional codes and no TUB is derived for the actual resulting NB-TC.…”

“…What mainly motivated our work is the theoretical issue of whether the odd-even constraint reduces interleaver gain. Raised in the early literature of turbo trellis-coded modulation (TTCM) [26][27][28][29], this issue has been largely overlooked, despite TTCM still being an active field [30][31][32]. In order to clearly address it, bounds should be derived on the average BEP of the odd-even uniform interleaver.…”

“…Παρόμοια γνωστά σχήματα στη διεθνή αρθρογραφία είναι η παράλληλα αλυσιδωτή τρέλις κωδικοποιημένη διαμόρφωση (parallel-concatenated trellis-coded modulation, PCTCM) των Benedetto et al [90], καθώς και ένα σχήμα BICM με τούρμπο κώδικες των Le Goff et al [141], και τα δύο της ίδιας περιόδου. ΄Εκτοτε, η TTCM έχει ενσωματωθεί στην ύλη πανεπιστημιακών συγγραμμάτων [6, §8.12-2] [142, §10.16], ενώ συνεχίζει να αποτελεί ενεργό πεδίο ερευνητικής δραστηριότητας [143][144][145][146]. Ξεκινούμε με την παρουσίαση της δομής της TTCM, συστατικό στοιχείο της οποίας αποτελούν οι τρέλις κώδικες.…”
