Title: DECODING METHOD, DEVICE SUITABLE FOR OVXDM SYSTEM AND OVXDM SYSTEM
Abstract:
Disclosed in the present application are a decoding method and a device suitable for an OvXDM system and an OvXDM system. During the decoding process, perform screening on access nodes in a trellis diagram corresponding to the system; an optimal path is jointly filtered by improving the calculation method of accumulative branch metric and combining weight factors; and the best decoding path is filtered by expanding the node with the smallest cumulative branch metric. Applying the solution of the present application in a decoding process of an OvXDM system with a large number of overlapping multiplexing times or a larger number of coding branches can reduce the system design complexity and calculation amount, make the system have a lower error rate and improve the performance.
