  Abstract

Conventional pragmatic TCMs need sector phase quantizer to apply Viterbi decoder which uses 3-bit soft decision. A symbol transformation applied to the incoming I-channel and Q-channel symbols allows to use Viterbi decoder without sector phase quantizer. We analyzed structure and performance of proposed decoder, and applied it to the turbo decoder. We know that the performance of proposed decoder is better than that of conventional decoder by 1[dB] because of increasing of Euclidean distance.
