Abstract: Based on the theory of matrix inverse approximate computation, a new amendatory decorrelating multiuser detection is provided. Comparing with the normal detection, this detection provide a lower complexity and its influence on bit-error probability and near-far effects can be very little. From a lot of simulated experiment, the result proved the algorithmic feasibility.

Key words: multiuser detection, multiple access interence (MAI), decorrelating detector
