Abstract :
In this paper we discuss the application of multilevel signaling techniques to the design of codes with spectral efficiencies between 0.75 and 1 bitldimension. We consider low rate turbo codes, along with l6QAM signal sets in a bit-interleaved coded modulation format, to achieve spectral efficiencies below 1 bitldimension. We then investigate the gains achievable with this approach compared to conventional binary signaling techniques.
