Abstract

The objective of this work is to present a multilevel convolutional coding method based on rings of integers modulo-m (generally m is a power of 2) which is suitable for Coded Modulation schemes. This new method of coded modulation is proposed because of the similarities between an m-ary phase shift keying modulation and the structure of a ring of integers modulo-m. Tables of multilevel transparent systematic convolutional codes with some of their characteristics are also presented. Finally, curves of decoding performance are shown for some convolutional codes suitable for coded 4-PSK and 8-PSK.
