摘要

提出了一种基于改进线性约束CMA的DS/CDMA系统快速收敛盲自适应多用户检测器。通过选择合适的线性约束代价函数，提高了算法抑制多址干扰和动态跟踪的性能。仿真结果表明，与同类算法相比，该算法在动态环境下收敛到稳态的速度更快。

Fast converging blind adaptive multiuser detectors with linearly constrained CMA for DS/CDMA systems

The paper presents a fast converging blind adaptive multiuser detector with modified linearly constrained CMA for DS/CDMA systems. By selecting a suitable linearly constrained cost function, the performance of the proposed algorithm is improved in terms of the capability of suppressing multiple access interference and dynamic tracing. Simulation results show that the proposed algorithm provides a faster convergence to reach a steady-state than similar algorithms in dynamic environments.
