Abstract :
A novel approach to combine turbo coding and high level modulation is introduced. Systematic trellis coded M-ary modulations are used as constituent codes. This scheme is a direct generalization to M-ary modulations of binary turbo codes. As a result, the whole iterative process is performed at M-ary symbol level. Analytical performance is derived and simulation results are presented.
