Abstract
Bandwidth efficient data transmission using trellis coded modulation (TCM) can significantly increase a digital communication link's reliability without sacrificing spectral efficiency. In this paper we discuss TCM on channels with impulse noise. The intentional partial band jammer with optimized duty cycle is analyzed analytically and taken as a worst case impulse noise interferer. It is shown that a new code design criterion, the effective length of a code becomes the central code parameter determining the performance of TCM. A number of new TCM codes are presented and their performance is calculated. It is shown that these codes fare significantly better than codes designed for additive white Gaussian noise channels.
