Abstract: The present disclosure relates to a method for coding on a time-space two-dimensional channels, in which the data bits to be transmitted are coded from the time-domain and the space-domain, respectively, to form time-space two-dimensional coding. the proposed coding operation in the space-domain and the time-domain can adopt different coding structures, coding rates and modulation constellations; subsequently, the system expresses each coding method with code words, merges the code words to form a space-time two-dimensional codebook, stores the codebook at both ends of the sending terminal and the receiving terminal; next, the sending terminal selects the coding structure according to the code words of the time-domain, and encodes each data stream according to time-domain coding rates, and eventually forms data blocks of an equal length in the time-domain through the rate matching. Then, the system selects different code word serial numbers, rate matching tables and space time slicing modes according to the requirements of different scenarios for transmission rates, latency and code error rate, as well as channel states and size of data blocks to be transmitted; eventually, when a Time Space Concatenated Coding Mode is adopted, the sending terminal firstly performs time-domain coding according to the time-domain slicing mode and the time-domain code words.
