US Patent 7593492 Combinational hybrid turbo-MUD

A high quality real-time Turbo-Mud processing system that chooses between a high complexity multi-user detectors that results in better estimates of the bit streams and computationally low linear-based-MUD/Turbo-MUD at each MUD window in each Turbo Iteration. In one embodiment this technique optimizes both the BER and the computational complexity of the receiver by using low complexity MUDs to reduce the number of symbols that the high complexity MUDs need to process. The present invention also provides an efficient means of estimating symbols transmitted in a multi-user environment in overloaded or super-saturated conditions.
