摘　　要：阐述了基于子空间跟踪算法的数据压缩最小均方误差(DCMMSE)盲多用户检测的基本原理.将PAST子空间跟踪算法应用于DCMMSE盲多用户检测,发现PAST子空间跟踪算法具有自然的数据压缩结构,适于DCMMSE盲多用户检测,在几乎不增加运算量的情况下即可实现DCMMSE盲多用户检测.仿真实验表明:基于PAST子空间跟踪算法的DCMMSE盲多用户检测具有良好的检测性能.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.
