Abstract: A method and a system for soft decision detection of multiple data stream integer-combinations are described, belonging to a technical field of communication and information systems, information theory and coding, and signal and information processing. The method includes steps of: step 1: sending a signal; step 2: receiving the signal; step 3: defining the multiple data stream integer-combinations; and step 4: computing a posterior probability for the multiple data stream integer-combinations. The method of the present invention has low complexity, parallel processing architecture and low processing delay, so that the decoding performance is close to the capacity limit. The present invention is particularly suitable for cell-free networks to achieve better efficiency in the utilization of the air interface and the backhaul link.

Abstract: The present disclosure provides an encoding method and apparatus, and relates to the field of communications technologies, to reduce an encoding latency and complexity, and the amount of computation of real-time construction. The encoding method includes: obtaining information bits; determining a puncturing pattern, where the puncturing pattern includes an element in a puncturing set and an element in a shortening set, and the puncturing set and the shortening set have no intersection set; and performing, by using the determined puncturing pattern, rate matching on data obtained after the information bits are encoded.
