Description: 这是一篇很好的有关信道估计的文章，
可以用来快速的了解信道估计的基本内容-and MAI induced by multiple-input, multiple-output channels. In particular, this article
reviews the typical inverse filter criteria (IFC) based algorithm, super-exponential algorithm,
and constant modulus algorithm along with their relations, performance, and improvements.
Several advanced applications of these algorithms are illustrated, including
blind channel estimation, simultaneous estimation of multiple time delays, signal-tonoise
ratio (SNR) boost by blind maximum ratio combining, blind beamforming for
source separation in multipath, and multiuser detection for direct sequence/code division
multiple access (DS/CDMA) systems in multipath. Platform: |

Description: 两种算法（LMS和RLS）实现CDMA系统盲多用户检测的仿真。结论验证了在加性高斯白招生信道下、同步DS-CDMA系统中接收机应用这两种盲多用户检测算法抑制多址干扰（MAI: multiple access interference）和码间串扰（ISI: inter symbol interference）的能力,仿真实验与理论推导相吻合。实验与理论都表明,RLS性能好于LMS，而LMS计算量明显小于RLS。-This paper discusses two algorithms (LMS and RLS) to achieve blind multiuser detection CDMA system simulation. Conclusion is verified in the Additive White Gaussian noise channel, the synchronous DS-CDMA system receiver applications both blind multiuser detection algorithm to suppress Multiple Access Interference（MAI）and Inter Symbol Interference (ISI) the ability of simulation is consistent with the theoretical. Both experiment and theory show that, RLS’s Performance is better than LMS, and the LMS ‘s computation was significantly less than RLS. Platform: |

Description: 盲多用户检测的LMS和RLS算法,在DS/CDMA通信系统中，为了解调出用户的有用信息，必须尽可能地抑制由其它用户扩频信号产生的多址干扰（MAI，Multiple Access Interference）。尽管最佳多用户检测器可以很好地抑制MAI，但其运算量会随着用户数的增加而呈指数增加。盲多用户检测技术可以在不知道其他用户信息的情况下检测出目标用户，所以在实际应用中有着十分重要的应用前景.-LMS and RLS algorithm Blind Multiuser Detection in DS/CDMA communication system, in order to demodulate the user useful information, must be possible to inhibit the spread spectrum signals generated by other users multiple access interference (MAI Multiple Access Interference) . Although the optimal multi-user detector can suppress MAI, but its computational complexity increases exponentially with the number of users increase. Blind Multiuser Detection technology can not know the other user information detected the target user, has a very important application prospect in practical applications. Platform: |
