Abstract :
This paper presents a family of low complexity concatenated two-state trellis-coded modulation (CT-TCM) schemes. A joint design strategy of all component codes is established. This leads to the so-called "asymmetrical and time-varying" structures. Compared with the existing turbo TCM codes, the proposed CT-TCM schemes have significantly reduced decoding complexity and demonstrate comparable or even better performance.
