Multi-user detection technology of CDMA system

It is Multi - User Detection, MUD that uses the orthogonality of signature among each User to eliminate multi-user mutual interference. Multi-user detection fully utilizes all users' information of signal causing multi-access interference to detect single user's signal which can reduce influence of multi-access interference and near-far effect, reduce the requirement of precision of power control in system, make use of link spectrum resources effectively, remarkably raise the system capacity.
