| Abstract: | The principle of data compression minimum mean square error（DCMMSE） blind multiuser detection based on subspace tracking algorithm was expounded.When the PAST subspace tracking algorithm was used for DCMMSE blind multiuser detection,it was discovered that the PAST subspace tracking algorithm had the natural structure of data compression and was suitable for DCMMSE blind multiuser detection and could achieve blind multiuser detection under the circumstance of almost no additional computation.The results of simulations showed that the performance of the DCMMSE blind multiuser detection based on PAST subspace tracking algorithm was perfect. |
