在这篇文章,最少的方形的经常的模量算法(LSCMA ) 与潜水艇空格途径被相结合, LSCM_SUB (Subspace ) 使失明适应多用户察觉 inmultipath 代码分割多重存取(CDMA ) 隧道被介绍。LSCMAin 的差的表演到噪音比率(SNR ) 的低信号被 LSCM_SUB 算法改进。建议 LSCM_SUB 算法的表演与 LSCMA 的相比。模拟结果证明那个 theLSCM_SUB 算法比 LSCMA 优异,特别在低 SNR。
In this article, the least square constant modulus algorithm (LSCMA) is combined with the subspace approach and a LSCM_SUB (Subspace) blind adaptive multiuser detection in multipath code division multiple access (CDMA) channels is presented. The poor performance of LSCMA in the low signal to noise ratio (SNR) is improved by the LSCM_SUB algorithm. The performance of the proposed LSCM_SUB algorithm is compared with that of LSCMA. Simulation results show that the LSCM_SUB algorithm is superior to the LSCMA, especially in the low SNR.
