In this paper, we consider designing low-density parity-check (LDPC) coded modulation systems to achieve unequal error protection (UEP). We propose a new UEP approach by partial su…
Block Markov Superposition Transmission: Construction of Big Convolutional Codes from Short Codes
Xiao Ma, Chulong Liang, Kechao Huang +1
A construction of big convolutional codes from short codes called block Markov superposition transmission (BMST) is proposed. The BMST is very similar to superposition blockMarkov…
