Method for coding on time space two dimensional channel

A method for coding based on a time-space two-dimensional channel, wherein the method comprises steps of:

• Step 1:
• sending, by a sending terminal, a pilot signal, estimating, by a receiving terminal, a channel, and selecting, according to requirements for a transmission time rate, a latency and a code error rate in different scenarios, appropriate code word serial numbers, modulation modes, rate matching tables and space time slicing modes for a time-domain coding and a space-domain coding, and then feeding back to the sending terminal together with a rank L of the channel;
• Step 2:
• slicing, when adopting a Time Space Concatenated Coding Mode in a time-space two-dimensional coding, data in space-domain by the sending terminal according to a feedback time-domain coding rate, and forming Mt data streams in parallel, wherein each of the Mt data streams has Kit bits, where 0≤i>Mt−1, Mt is a number of data streams resulted from the sliced data in the space-domain, and Kit is a number of bits of each of the Mt data streams;
• Step 3:
• selecting, according to a code word of time-domain, a coding structure by the sending terminal, and coding each of the Mi data streams according to a time-domain coding rate, and eventually forming, by a rate matching, data blocks of an equal length in the time-domain;
• Step 4:
• slicing, according to a feedback space-domain coding rate, data in the time-domain by the sending terminal, and forming Ms data streams in parallel, wherein each of the M8 data streams has Ki8 bits, where 0≤i≥ Ms−1, Ms is a number of data streams resulted from the sliced data in the time-domain, and Kis is a number of bits of each of the Ms data streams;
• Step 5:
• selecting, according to a code word of the space-domain, the coding structure by the sending terminal, and coding each of the Ms data streams according to a space-domain coding rate, and eventually forming, by the rate matching, data blocks containing L bits in the space-domain;
• Step 6:
• modulating, according to a feedback modulation mode, B bits adjacent to the space-domain coding rate, the data in the space-domain by the sending terminal and forming the Mt data streams in parallel, wherein each of the Mt data streams has the Kit bits, where 0≤i≥Mt−1, L is a number of layers, and B is a number of bits per symbol;
• Step 7:
• slicing, when adopting a Space Time Concatenated Coding Mode in the time-space two-dimensional coding, the data in the time-domain by the sending terminal according to the feedback space-domain coding rate, and forming the Ms data streams in parallel, wherein each of the Ms data streams has the Kis bits, where 0≤i≥Ms−1;
• Step 8:
• selecting, according to the code word of the space-domain, the coding structure by the sending terminal, coding each of the Mt data streams according to the space-domain coding rate, and eventually forming, by the rate matching, the data blocks containing L bits in the space-domain;
• Step 9:
• slicing, according to the feedback space-domain coding rate, the data in the space-domain by the sending terminal and forming the Mt data streams in parallel, wherein each of the Mt data streams has the Kit bits, where 0≤i≥Mt−1;
• Step 10:
• selecting, according to the code word of the time-domain, the coding structure by the sending terminal, and coding each of the Mt data streams according to the time-domain coding rate, and eventually forming, by the rate matching, the data blocks of the equal length in the time-domain;
• and
• Step 11:
• modulating, according to the feedback modulation mode, the B bits adjacent to each other in the time-domain to form L symbol streams.
