Development of Cognitive Function Evaluation Contents for Mobile Based on MMSE-DSMild cognitive impairment (MCI) is considered as the intermediate stage between the cognitive changes of normal aging and dementia, which is marked by decline in memory but preserved ability to......
摘要: This paper investigates the performance of MMSE detection of DS-CDMA signals in frequency selective Rayleigh fading channels. The performance of some typical implementations of the MMSE receiver are shown to be quite sensitive to the rate of fading on a frequency selective channel...
[0009] To address the need for an MMSE receiver capable of receiving DS-CDMA signals with transmit diversity, several MMSE receivers are provided herein. In particular, three different MMSE receivers—one for OTD, one for STS, and one for STTD are provided. [0010] In an alternate embodiment...

1张硕1钟子发史英春张浩(解放军电子工程学院,安徽合肥230037)在分析MMSE估计准则特性的基础上,从最优匹配的角度提出了一种基于MMSE最优匹配合并的DS-CDMA单用户时延估计算法。算法通过对用户扩频序列延迟混叠向量进行分段估计,分段匹配滤波以及最优合并的方式,解决了传统MMSE时延估计中由于幅度不匹配对估计性能造成的影响...
DS/CDMA receiverdirect-sequence spread spectrumA direct-sequence spread spectrum (DS/SS) receiver for suppressing multiple-access interference in direct-sequence code-division multiple-access (DS/CDMA) communication systems is introduced. The proposed receiver does not require knowledge of other users' ...
给出了基于差分最小均方误差 (DMMSE)准则的短扩频序列 DS-CDMA自适应多用户检测算法。DMMSE准则避免了跟踪信道衰落 ,而是有效的利用了两个连续符号增益的微小变化来调整接收机 ,该准则在快衰落信道条件下显示了良好的鲁棒性。仿真结果也证明了算法的合理性和有效性。 著录项 来源 《吉林大学...
