Novel ternary line codes employing Trellis Coded Modulation

The goal of a communication system is to optimally utilise the scarce spectrum and the energy required to transmit information while maintaining a specific quality of service. In this paper, it is proposed to communicate information by using new ternary line coders with code rates R = 1/2, 2/3 and 3/4 as invented by Aygolu and Panayirci [1]. The encoding/decoding is based on the convolutional coding and Trellis-Coded Modulation (TCM) procedures. The aim of this research work is to examine and compare the performances of the new ternary line coding systems with respect to the Paired Selected Ternary conventional system in Gaussian channels. Simulation results show gains of the new ternary line code systems, both as proposed by Aygolu and Panayirci [1] and when Trellis-Coded Modulation is employed, compared with the Paired Selected Ternary line code system.
