Resumen:
A new coded niodulation technique for signal sets designed contbining wavelet functionsand M-quadrature amplitude modulation (MQAM) is presented. Trellis-coded modulation (TCM)is iinpleniented using thc ring of integers modulo-Q as the algebraic structure of the multilevelconvolutional encoder. These schemes are s u i t e for adaptive time-frequency unequal errorprotcction. multiple-access and multiplexing, as well as being effective replaccinents for existingschcmes. Wavelet-based ring-TCM schemes and MQAM ring-TCM schemes are first presented,and then combined to constitute a concatenated ring-TCM scheme. Thc concatenaled schemeshows a coding gain of around 8 dB over uncoded BPSK, and does not require iterative decoding.
