Power and confidence ordered low complexity soft turbomud with voting system

Process transmission on a simultaneous digital modulation interferer and the same frequency, and the performance of the point-to-multipoint connection system by which load was applied heavily and by which the overload was carried out is optimized, The real-time multiuser detection (MUD) receiver which realizes a repetitive TurboMUD receiver using tree pruning, including reliance ordering, electric power ordering, and a vote procedure (330). 1st repeatedly, a user index can be set in order according to received power. A single user decoder (340) is provided with the future soft determination or belief values for which a voting system is repeatedly utilized as a soft input. Vote (330) is attractive calculatively, and the bank of a decoder operates with a software value, improves performance, and enables it to reduce the number of TurboMUD repetition. The bank of a soft output error correction decoder generates the set by which the soft determination corresponding to the channel bit transmitted by each interfering user or a belief value has been improved. It is used in order that the belief value from the bank of a decoder may set a user index in order, and the MUD detector (320) by which tree pruning was carried out operates first as a most reliable symbol, and enables it to improve the likelihood that pruning is right. Conditions are fulfilled, and future reliance ordering and a presumed improvement are generated until repetitive operation is completed.
