Abstract: Provided in the present invention is a trainable joint channel estimation, detection and decoding method suitable for a URLLC-MIMO system. In a URLLC-MIMO system, after mapping an LDPC codeword into modulation symbols, a transmitting end uniformly allocates the modulation symbols to different transmitting antennas for transmission; and a receiving end constructs a joint channel estimation, detection and decoding problem model and solving frame based on an MAP criterion, then deeply unfolds the frame into a neural network, performs offline training on adjustable parameters in the neural network, and finally uses the trained neural network to acquire codeword bits online. Compared with a traditional reception method, by means of the present invention, the BLER performance of a system can be significantly improved, and system latency is also reduced, thereby saving on signaling overheads.
