| dc.description.abstract | 在本篇論文中，探討了頻域預編碼式非正交分頻多工(spectrally precoded nonorthogonal frequency-division multiplexing, SP-NOFDM)系統等相關技術，首先，我們研究了頻域預編碼式非正交分頻多工的頻譜特性，在預先設計某個整數參數J之下，為了確保功率頻譜的旁波(sidelobes)衰減的程度是近似 f-2J-2，發展了對於頻域預編碼(spectral precoding)的廣義限制條件，且此限制條件適用於沒有限制的保護比例(guard ratio)、預設的頻率間隔係數(frequency spacing factor)以及任意的統計輸入資料的頻域預編碼式非正交分頻多工訊號型式，除此之外，我們進一步提出了兩種不同但滿足此限制的編碼。第二，我們推導了頻域預編碼式非正交分頻多工的通道容量(channel capacity)解析性。第三，我們為頻域預編碼式非正交分頻多工系統接收端設計了基於線性最小均方差(linear minimum mean square error)估計器。最後，結果顯示頻域預編碼式非正交分頻多工比起沒有編碼的正交分頻多工(orthogonal frequency-division multiplexing with cyclic prefix)除了可以有效地壓抑旁波，還能得到較高的頻譜緊密度以及較佳的頻譜效益(spectral efficiency)。 | zh_TW |
| dc.description.abstract | Spectrally precoded nonorthogonal frequency-division multiplexing (SP-NOFDM) techniques is investigated in this thesis. First, the spectral characteristic of SP-NOFDM is studied. In order to guarantee power spectral sidelobes decaying asymptotically as f-2J-2 with J being a predesigned integer-valued parameter, a general constraint on spectral precoding is developed for SP-NOFDM signal formats with unconstrained guard ratios, presettable frequency spacing factor and arbitrary input data statistics. Moreover, two different precoders are proposed to satisfy this constraint. Second, the channel capacity of SP-NOFDM systems is analytically derived. Third, the linear minimum mean square error receiver is designed for SP-NOFDM systems. Finally, it is shown that the proposed SP-NOFDM signals can suppress sidelobe powers effectively and thus achieve higher spectral compactness than nonprecoded rectangularly-pulsed orthogonal frequency-division multiplexing with cyclic prefix (CP-OFDM) signals. | en |
