| dc.description.abstract | 不必用到差分編碼的非同調籬柵編碼調變在1996年被提出。非同調籬柵編碼調變通常用在有固定載波相位的AWGN通道中。然而，存在快速改變載波相位時，非同調籬柵編碼調變的錯誤效能並不理想。
本論文主要是考慮非同調籬柵編碼調變在這種快速改變相移的通道中的解碼。我們提出幾種解碼演算法，並以電腦模擬來顯示其錯誤效能的改進。 | zh_TW |
| dc.description.abstract | Noncoherent trellis coded modulation(NTCM), for which differential encoding is not used, was proposed in 1996. The channel considered by NTCM is AWGN channels with constant carrier phase. However, if there exists rapidly changing carrier phase, the error performance of NTCM is unsatisfactory.
In this thesis, we investigate the decoding of NTCM in the presence of rapidly changing carrier phase. Several decoding algorithms are proposed. The improvement of error performance are verified by computer simulations. | en_US |
