| dc.description.abstract | 在同調偵測下，用多層編碼的區塊編碼調變(BCM)是具有頻寬效益的編碼架構。最近一個新的用於非同調偵測的區塊編碼調變架構，稱作非同調區塊編碼MPSK (noncoherent block coded MPSK , NBC- MPSK)已被提出。非同調區塊編碼MPSK可輕易的由選擇適當的成份碼來設計。更進一步的，基於A*解碼法的用於非同調區塊編碼MPSK的最大相似解碼法也已被提出。
在本篇論文中，我們首先修正其最大相似解碼演算法以更進一步降低解碼複雜度，並與另一個近似最佳的具線性複雜度的非同調多階層解碼器做比較。接著我們提出用於非同調區塊編碼MPSK於多重天線系統下的推廣的最大相似以及降低複雜度的解碼演算法。更進一步的，我們將效能與文獻上的數種編碼架構做比較與整理。 | zh_TW |
| dc.description.abstract | For coherent detection, block coded modulation encoded by multilevel coding is a bandwidth efficient scheme. Recently, a novel block coded modulation scheme for noncoherent detection, called Noncoherent Block-Coded MPSK (NBC-MPSK), was proposed. The NBC-MPSK can be easily designed by properly choosing binary linear block codes as the component codes. Moreover, a maximum-likelihood (ML) decoding algorithm based on A* decoding algorithm for NBC-MPSK was also proposed.
In this thesis, we first modify the ML decoding algorithm to further reduce the decoding complexity, and compare it with a near-optimal linear-complexity noncoherent multistage decoder. Then we propose ML and complexity-reduced decoding algorithms for the generation of NBC-MPSK on multi-antenna system. Furthermore, we compare the error performance with several codes in the literature. | en_US |
