dc.description.abstract	對於同調解碼，區塊編碼調變（BCM），是一種有頻寬效益的編碼技術，而最近出現一個新的用於非同調解碼之區塊編碼調變，叫非同調區塊編碼調變(NBC-MPSK)，它提供了彈性方便的非同調區塊碼設計方法。然而對於此架構所設計出來的某些碼，用維特比法則解碼太複雜了，因為柵狀解碼時需要太多狀態（states）。 A*解碼法目前已經被使用在線性區塊碼的最大相似解碼上，它可以減少搜索路徑，非常適合用來解區塊碼，在本篇論文中，我們將探討將A*解碼法用在非同調區塊編碼調變上，電腦模擬結果展現了令人滿意的效能。	zh_TW
dc.description.abstract	For coherent detection, block coded modulation is a bandwidth efficient technique. Recently, a novel block coded modulation scheme for noncoherent detection, called noncoherent block coded MPSK (NBC-MPSK) is proposed. The NBC-MPSK provides flexible schemes in designing noncoherent block codes. However, for some codes of NBC-MPSK, the Viterbi decoding is too complicated because the decoding trellis need too many states . A* algorithm has been used to implement maximum-likelihood soft-decoding of linear block codes. It can minimize the search edges. In this thesis, we use A* algorithm for the decoding of NBC-MPSK. Simulation results show that this decoding algorithm has satisfactory error performance.	en_US
