| Abstract: | Iterative multi-user detection technology is another application of "iterative thought" which derived from turbo decode algorithm. The iterative multi-user detection decoder considers turbo decode and multi-user detection jointly, which has become a focus in communication research recently. The result is indicated that iterations of the system are used to attain large performance improvements, which is near single user performance. |
