One kind of fast decoding method, apparatus and OvXDM system applied to OvXDM system

摘要

The present application discloses a fast decoding method, apparatus and OvXDM system applied to the OvXDM system. The method does not need to go through every state node and its extended route in the decoding process, but can extend some state nodes and routes by reordering the measures, greatly reducing decoding complexity and decoding. Increases efficiency. The decoding complexity does not increase rapidly with the increase in the number of duplicate multiplexes K as in the traditional decoding plan, and the contradiction between the demands of spectrum efficiency, decoding complexity, and decoding efficiency is solved.
