One type of decoding method, equipment and system applied to OvXDM systems

摘要

This application discloses a decoding method for an OvXDM system, including: generating an augmented matrix B related to a received symbol information sequence; performing singular decomposition on the augmented matrix B; and performing decoding by using a total least square method, to obtain a decoded output information sequence. This application further discloses an OvXDM system. In a specific implementation of this application, decoding is performed by using the total least square method. This resolves the problem in a conventional decoding method, for example, Viterbi decoding, that a large number of storage resources (path storages and distance storages) are needed, the decoding complexity increases drastically as a number of times of overlapping increases, and real-time performance of decoding output is relatively low because symbol-by-symbol decoding is performed in a decoding process. In this application, a decoding result can be obtained more accurately when a signal encounters noise interference. This simplifies the decoding process, saves system resources, reduces the decoding complexity, and ensures system performance while improving the decoding efficiency.
