Coded modulation based on rings of integers modulo-q. 2. Convolutional codes

摘要

The authors presents a coded modulation method based on multilevel convolutional codes defined over finite rings of integers. A previously developed theory is applied to multilevel convolutional codes. Some tables of convolutional codes defined over rings of integers modulo-q are obtained. Curves of soft- and hard-decision decoding performance are also shown.
