本論文探討結合區塊編碼調變(BCM)與具通道估測(channel estimation)之空時區塊碼。利用連結訓練符元之通道估測讓空時區塊碼很容易的在接收端進行非同調檢。我們討論使用不同長度之區塊編碼調變與具通道估測之空時編碼連結。最後將此系統與么正空時調變(USTM)在半平穩衰退通道(quasi-static flat fading channel)中之效能加以比較。 In this thesis, combing block coded modulation (BCM) and space-time block coding (STBC) with channel estimation is discussed. Taking advantage of the channel estimation using training symbols, noncoherent detection can be easily employed by STBC.The impact of STBC using training symbols concatanated with different block length of BCM is also investigate. Finally, we compare the system with unitary space-time modulation in the quasi-static flat fading channel
