語音識別中的說話人自適應研究.nh 1.MAp和MLLR算法比較 文章在討論由說話人引起的聲學差異基礎上,研究兩種基于模型 的自適應算法:最大似然線性回歸(州壓LR)和最大后驗概率(MAp)。 實驗結果表明,不論采用哪種自適應都能使識別率有一定的提升。兩 種算法之間的差異性在于MAp具有良好的漸進性,但收斂性較差, 而MLLR在很大程度上改善了收斂特性,但其漸進特性卻不如MAp。 文章討論了在側汰P自適應中,初始模型參數的先驗知識對自適 應效果的影響,以及在MLLR中,回歸類對自適應效果的影響。文 章還進一步研究了采用兩種算法的累加自適應效果,從結果看MAp 和MLLR結合的方法比單獨使用M[Ap和MLLR的效果要好。文章 還對包括基于特征層的歸一化算法和用于基于聲學模型的MLLR算 法等效性進行討論,并給出了統一的算法框架。

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.
