Fast sidelobe decaying constraints are developed for both interleaved and localized subcarrier allocation schemes. It is shown that when there is no spectral precoding, the proposed ANC-SC-FDMA provide much higher spectral compactness than conventional SC-FDMA without trading off system complexity and PAPR characteristics remarkably. Furthermore, by specifying anchor-symbol value to zero, ANC-SC-FDMA can provide enhanced error performance. After spectral precoding technique is applied, SP-ANC-SC-FDMA can achieve spectral compactness prevalence than ANC-SC-FDMA.Contents Abstract i Contents ii List of Figures iv 1 Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 1.1 SC-FDMA Systems . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .1 1.2 Review of Sidelobe Suppression Schemes . . . . . . . . . . . . . . . . . . . . . . . 3 1.2.1 Spectral Precoding Technique for OFDMA . . . . . . . . . . . . . . . . . . . . . . 3 1.2.2 Sidelobe Suppression Schemes for SC-FDMA . . . . . . . . . . . . . . . . . . . 4 1.3 Thesis Motivation, Overview, and Contributions . . . . . . . . . . . . . . . . . . . . 6 2 System Model, Signal Model and Fast Sidelobe Decaying Constraints . . . . .8 2.1 System Model . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 2.2 Signal Model . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9 2.3 Fast Sidelobe Decaying Constraints . . . . . . . . . . . . . . . . . . . . . . . . . . 11 3 Spectrally Precoded IFDMA With Anchor-Symbol Insertion . . . . . . . . . . . . 15 3.1 Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15 3.2 Anchor-Symbol Insertion Design . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15 3.3 Spectral Precoding Matrix Design . . . . . . . . . . . . . . . . . . . . . . . . . . . . 17 3.4 Numerical and Simulation Results . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20 3.4.1 Power Spectral Compactness Characteristics . . . . . . . . . . . . . . . . . . 21 3.4.2 PAPR Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 23 3.4.3 Error Performance Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . 24 3.5 Chapter Summary . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 26 4 Spectrally Precoded LFDMA With Anchor-Symbol Insertion . . . . . . . . . . . 27 4.1 Introduction . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27 4.2 Anchor-Symbol Insertion Design . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 27 4.3 Spectral Precoding Matrix Design . . . . . . . . . . . . . . . . . . . . . . . . . . . . 29 4.4 Numerical and Simulation Results . . . . . . . . . . . . . . . . . . . . . . . . . . . . 31 4.4.1 Power Spectral Compactness Characteristics . . . . . . . . . . . . . . . . . . 32 4.4.2 PAPR Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 35 4.4.3 Error Performance Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . 36 4.5 Chapter Summary . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 38 5 Conclusion . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 39 Bibliography . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 411418671 bytesapplication/pdf論文公開時間:2017/07/15論文使用權限:同意有償授權(權利金給回饋學校)單載波分頻多重存取頻譜預編碼循環字首頻葉削減峰均值比應用錨符元插入技術之頻譜預編碼單載波分頻多重存取Spectrally Precoded SC-FDMA With Anchor-Symbol Insertionthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/264266/1/ntu-103-R01942051-1.pdf
