Abstract :
A new multilevel coding (MLC) scheme invoking sphere packing (SP) modulation is proposed, where the SP arrangement is jointly designed with a space time block code (STBC) for the sake of attaining an additional space diversity gain. An iterative multistage decoding (MSD) aided multilevel sphere packing demodulator is proposed for attaining a high decoding performance at a low decoding complexity, when communicating over a correlated Rayleigh channel. The appropriate design of a 4-dimensional (4D) sphere packing bit-to-SP-symbol mapping scheme and the beneficial choice of the individual coding rates of the MLC scheme allows us to provide an unequal error protection capability, which is often required for efficient audio or video transmissions.
