摘要

在本文中，我们提出了Davidon-Fletcher-Powell (DFP)方法来解决多用户检测问题。可以看出，DFP通过减少迭代次数和残差显著提高了MUD的性能。该技术还可以快速收敛到最优值。仿真结果表明，在信噪比为3db的情况下，DFP方法的性能提高了30%。

Space-time multi-user detection techniques for CDMA communication systems

In this paper, we have proposed the method of Davidon-Fletcher-Powell (DFP) to solving the problem of multiuser detection (MUD). It can be shown that DFP significantly improves the performance of MUD by reducing the number of iterations and residual error. This technique also provides rapid convergence to the optimal value. The simulation shows that the DFP method can improve up to 30% of performance with 3-dB SNR.
