 Title: 籬柵編碼正交振幅調變的非同調解碼;Noncoherent Decoding for Trellis Coded Quadrature Amplitude Modulation Authors: 陳良圖;Liang-Twu Chen Contributors: 電機工程研究所 Keywords: 非同調籬柵編碼調變;正交振幅調變;非同調解碼演算法;noncoherent decoding algorithms;noncoherent trellis coded modulation;quadrature amplitude modulation Date: 2002-06-14 Issue Date: 2009-09-22 11:47:42 (UTC+8) Publisher: 國立中央大學圖書館 Abstract: 在這篇論文裡，我們研究籬柵編碼正交振幅調變的非同調解碼 在第一章裡，我們對本論文之研究內容作一簡介。 在第二章裡，我們回顧了相關的非同調籬柵編碼調變架構與非同調解碼演算法。 第三章裡，我們提出一種修正UngerBoeck所提傳統籬柵編碼正交振幅調變的方法，設計了多種適合非同調解碼的籬柵編碼正交振幅調變架構，也驗證了這些架構的非同調解碼之錯誤效能，並與現有架構之錯誤效能做比較。 在第四章裡，我們將一些已使用在非同調籬柵編碼相位調變架構的非同調解碼演算法加以延伸並修改成適用於籬柵編碼正交振幅調變架構的非同調解碼演算法。這些解碼演算法使用於我們設計的非同調籬柵編碼正交振幅調變架構，都經電腦模擬予以驗證，也分析比較各非同調演算法間錯誤的效能。 In this thesis, we study the noncoherent decoding for trellis coded quadrature amplitude modulation. In Chapter 1, we introduce overall contents of this thesis. In Chapter 2, we review some relative noncoherent trellis coded modulation structures and noncoherent decoding algorithm. In Chapter 3, we propose a method by modifying Ungerboeck’s trellis coded quadrature amplitude modulation structure. We construct various trellis coded quadrature amplitude modulation structures for noncohernt decoding. We also verify the error performance of the proposed structures and compare the performance between the proposed structure and the existed structure. In Chapter 4, we extend and modify the noncoherent decoding algorithms that are used in trellis coded phase modulation system for trellis coded quadrature amplitude modulation structures. The algorithms for the proposed and the existed trellis coded quadrature amplitude modulation structures are verified by computer simulation, we also analysis and compare the error performance between them.
