| Abstract(in English) | Recently, turbo trellis-coded modulation which is combination of trellis-coded modulation and turbo codes attracts researcher's attention. Trellis-coded modulation(TCM) provides high bandwidth efficiency, and turbo codes provide excellent BER performance. Moreover, multidimensional turbo TCM which is combination of multidimensional TCM and turbo codes is under study. Turbo TCM was applied to PSK signal sets based on binary generators. This scheme has high flexbility of signal sets construction, high bandwidth efficiency and much coding gain. In this paper, we applied turbo TCM to multidimensional QAM(Quadrature Amplitude Modulation) signal sets which have higher bandwidth efficiency, and made comparison based on some criteria. As a result, we were able to obtain much coding gain. |
