报告摘要：

In this talk, two principles to construct good codes are revealed: repetition (diversity) and superposition (multiplexing) whereby repetition increases reliability and superposition increases efficiency. These two principles are illustrated by the so-called block Markov superposition transmission (BMST) technique. The encoding process of BMST can be as fast as that of the basic codes, while the decoding process can be implemented as an iterative sliding-window decoding (SWD) algorithm with a tunable delay. More importantly, BMST codes have a simple lower bound relating to the transmission memory and the performance of the short code. Simulations as well as threshold analysis show that the lower bounds can be matched with a moderate decoding delay in the low bit-error-rate (BER) region, implying that the iterative SWD algorithm is near optimal. BMST codes can also admit a two-phase decoding (TPD) algorithm, whose performance in the low BER region can be upper bounded. It has been verified by simulation that the construction approach is applicable not only to binary phase-shift keying (BPSK) modulation but also to bit-interleaved coded modulation (BICM), spatial modulation, continuous phase modulation (CPM) and intensity modulation in visible light communications (VLC).
