Abstract: In this paper, a method for joint source-channel coding (JSCC) based on concatenated spatially coupled low-density parity-check (SC-LDPC) codes is investigated. A construction consisting of ...
Abstract: In this letter, an adaptive decoding algorithm with a variable sliding window for joint source-channel coding (JSCC) scheme based on double spatially coupled low-density parity-check ...
For decades, Elizebeth Smith Friedman worked in near-total secrecy, cracking codes that shaped the outcome of two world wars. Recently declassified, the full extent of her story is still coming to ...
