| dc.description.abstract | 在2000年，一個使用相位鍵移(phase shift-keying, PSK)訊號之么正空時調變(unitary space-time modulation, USTM)之系統化設計被提出。在此篇論文中，我們提出三種使用振幅相位鍵移(amplitude phase-shift keying)訊號之么正空時調變架構。我們使用電腦去搜尋具有最大分集乘積 ζ的么正空時碼。相較於過去所提出的架構，在第一和第三種架構下，我們搜尋到有著較佳分集乘積的么正空時碼。模擬結果證實我們所搜尋到的么正空時碼相較於之前所提出的架構，有著較佳的錯誤率效能表現。 | zh_TW |
| dc.description.abstract | A systematic design of unitary space-time modulation using phase shift-keying (PSK) signals was proposed in 2000. In this thesis, we propose three schemes of unitary space-time modulation (USTM) that use amplitude phase-shift keying (APSK) signal points. We utilize the computer to search codes in USTM that maximize the diversity product ζ. Several of searched codes in Scheme 1 and Scheme 3 have better diversity product ζ than the codes for the proposed scheme in 2000. Simulation results confirm that our searched codes have better error performances than the proposed scheme in 2000. | en_US |
