A comparison of turbo codes using different trellis terminations

Research output: Contribution to journalArticle

Abstract

Abstract in Undetermined
This paper investigates the incidence of trellis termination on the
performance of turbo codes and accounts for the performance degradation
often experienced in the absence of trellis termination. Analytical upper
bounds on the performance for the ensemble of turbo codes using different
trellis termination strategies as well as performance results obtained by
computer simulation are presented. In the case of uniform interleaving, the
performance differences between various termination methods are relatively
small, except when using no trellis termination at all.
