In this thesis , we first introduce give the definition of hidden markov models . then the methods to solve the three basic problems in the application of hidden markov models are introduced , namely three basic arithmetic : forward - backward algorithm , viterbi algorithm , baum - welch algorithm . also we present commonly model of hidden markov processes dynamic system 在這篇論文中,首先給出了隱馬爾科夫模型的定義,接著介紹了隱馬爾科夫模型實際應用中所面臨的三大基本問題的解決方案,即隱馬爾科夫模型三大基本算法:前向一后向算法、 viterbi算法、 baum ? welch算法。

Due to existing signal processing technology ’ s shortage such aslow measurement , narrow measurement range precision and other poor performance , we introduced a high - precise signal processing technology : firstly , to get power spectrum with hanning windowed welch modified periodogram , search its peak value frequency ; secondly , to apply zooming analysis via goertzel algorithm ; at last , to get a highly precise doppler frequency with energy centrobaric rectifying algorithm 。 the simulating result indicated that this technology introduced could get accurate doppler frequency 。 depending on above discussed technology , we designed a signal processing scheme , and developed a signal processing system . the running result showed high performance , verified the feasibility and reliability of the highly precise signal processing technology introduced . in a word , the technology improved ldv ’ s performance such as measurement precision , measurement range , dynamic response time 。 and it will have a wide application foreground 針對存在的缺點,本文提出了一種應用于激光多普勒測速的高精度信號處理技術,即首先利用加hanning窗的welch修正周期圖算法得到信號功率譜,搜索其譜峰值頻率,接著利用goertzel頻譜細化算法對搜索的譜峰進行細化分析,再引入能量重心頻譜校正算法對細化后的譜峰進行校正分析,從而將離散頻譜分析算法、頻譜細化算法和頻譜校正算法三者有機結合起來,充分發揮各自的優點:通過加hanning窗的welch修正周期圖算法快速得到功率譜及峰值頻率,通過goertzel算法獲得分析頻帶的高分辨率頻譜,然后通過能量重心校正算法對細化后的頻譜進行高精度校正,這樣不僅保證了算法的高效性,而且大大提高了分析的精度。
