Abstract:	本論文的主旨為建構以MPSK做調變，可適用於非同調解碼的多層次編碼調變，此編碼調變使用的非同調編碼能夠比使用區塊編碼的多層次編碼調變使用非同調解碼得到更接近同調解碼的錯誤效能。最後，將多層次的概念建構以QPSk做調變，可適用非同調解碼的籬柵編碼調變與時空編碼調變，一樣可達到良好的錯誤效能。 In this paper，the thesis constructs a multilevel coded modulation for noncoherent decoding based on MPSK. The coded modulation using noncoherent encoding is more approaching to the error performance of coherent than block multilevel coded modulation using noncoherent decoding. At last，we use the same concept to construct a multilevel trellis coded modulation and space time coded modulation for noncoherent decoding based on QPSK，and it can have a good error performance，too.
