Turbo code optimization based on terahertz communication

In order to achieve reliable terahertz communication at ultra-high data rates, this paper proposes Turbo coding with S-random interleaver combining circular propagation constraint and circular shift, firstly, the overall structure is optimized mainly by using parallel loops for multi-core computation and reserving memory in advance, secondly, the coding structure is optimized, then S-random interleaver with circular propagation constraint and circular shift is used, and finally, the decoding The structure is optimized. Through simulation experiments, it can be concluded that the proposed Turbo coding method improves the coding operation rate and reduces the BER and transmission delay.
