语音识别中的说话人自适应研究.nh 1.Map和MLLR算法比较 文章在讨论由说话人引起的声学差异基础上，研究两种基于模型 的自适应算法:最大似然线性回归(州压LR)和最大后验概率(Map)。 实验结果表明，不论采用哪种自适应都能使识别率有一定的提升。两 种算法之间的差异性在于Map具有良好的渐进性，但收敛性较差， 而MLLR在很大程度上改善了收敛特性，但其渐进特性却不如Map。 文章讨论了在侧汰P自适应中，初始模型参数的先验知识对自适 应效果的影响，以及在MLLR中，回归类对自适应效果的影响。文 章还进一步研究了采用两种算法的累加自适应效果，从结果看Map 和MLLR结合的方法比单独使用M[ap和MLLR的效果要好。文章 还对包括基于特征层的归一化算法和用于基于声学模型的MLLR算 法等效性进行讨论，并给出了统一的算法框架。

The rapid growth in mobile communications has led to an increasing demand for wide- band high data rate communications services. In recent years, Distributed Antenna Systems (DAS) has emerged as a promising candidate for future (beyond 3G or 4G) mobile communications, as illustrated by projects such as FRAMES and FuTURE. The architecture of DAS inherits and develops the concepts of pico- or micro-cell systems, where multiple distributed antennas or access points (ap) are connected to and con- trolled by a central unit.

The goal of this book is to provide a concise but lucid explanation and deriva- tion of the fundamentals of spread-spectrum communication systems. Although spread-spectrum communication is a staple topic in textbooks on digital com- munication, its treatment is usually cursory, and the subject warrants a more intensive exposition. Originally adopted in military networks as a means of ensuring secure communication when confronted with the threats of jamming and interception, spread-spectrum systems are now the core of commercial ap- plications such as mobile cellular and satellite communication.

Wireless communications, together with its applications and underlying technologies, is among today’s most active areas of technology development. The very rapid pace of im- provements in both custom and programmable integrated circuits for signal processing ap- plications has led to the justfiable view of advanced signal processing as a key enabler of the aggressively escalating capacity demands of emerging wireless systems. Consequently, there has been a tremendous and very widespread effort on the part of the research community to develop novel signal processing techniques that can fulfill this promise.
