Esquemas de modulação codificada em treliça multiária (TCM) foram estudados para uso com sistemas de comunicação de rádio digital. Entre esses esquemas TCM, já relatamos a constelação de sinal ideal de um esquema de modulação de amplitude e mudança de fase (APSK) codificado em treliça de taxa 3/4 (TC) e calculamos a distância euclidiana mínima: dsem. Neste artigo, avaliamos outros parâmetros de desempenho: Nsem e taxa de erro de bit (BER) sobre um canal de ruído gaussiano branco aditivo, e investigar ainda mais as várias constelações de sinais de esquemas de taxa 4/5 TC 32-APSK. Verifica-se que os desempenhos BER das constelações de sinais do tipo circular são superiores aos do tipo retangular no TC 16-APSK, e uma constelação de sinais do tipo circular (24,8) é superior a outras constelações no TC 32-APSK. .

Abstract: Multi-ary Trellis-Coded Modulation (TCM) schemes have been studied for use with digital radio communication systems. Among these TCM schemes, we have already reported the optimum signal constellation of a rate-3/4 trellis-coded (TC) 16-ary Amplitude and Phase Shift Keying (APSK) scheme and computed the minimum Euclidean distance: dfree. In this paper, we evaluate other performance parameters: Nfree and bit error rate (BER) over an additive white Gaussian noise channel, and further investigate the various signal constellations of rate-4/5 TC 32-APSK schemes. It is found that the BER performances of circular-type signal constellations are superior to that of rectangular-type in the TC 16-APSK, and a (24,8) circular type signal constellation is superior to other constellations in the TC 32-APSK.
