dc.description.abstract | 大規模機器型通訊 (massive machine type communication) 是第五代行動通訊系統 (5G) 中的主要場景之一。為了滿足大規模機器型通訊的需求,一個具有大規模連結 (massive connectivity)、低峰均功率比 (low peak-to-average power ratio) 和低子頻帶外散射 (low out-of-subband emission) 傳輸方法是至關重要的。因此我們研究了非正交多重接取與新波型的結合。本篇論文提出了稀疏碼多重接取 (sparse code multiple access) 與循環脈衝形正交分頻多工 (CPS-OFDM) 結合以因應第五代行動通訊系統大規模機器型通訊場景。為了結合稀疏碼多重接取與循環脈衝形正交分頻多工,我們提出了稀疏碼多重接取碼書設計的准則並設計了一組碼書。使用本論文提出的碼書可以很好地保有循環脈衝形正交分頻多工所宣稱的低峰均功率比與低子頻帶外散射的實體層特性。模擬結果顯示,與其他現有的基於稀疏碼多重接取與正交分頻多工的方案相比,具有更好的位元錯誤率 (bit-error rate) 和頻譜效率 (spectral efficiency)。 | zh_TW |
dc.description.abstract | Massive machine type communication (mMTC) is one of the major scenarios in the fifth generation wireless systems (5G). To meets the requirements of mMTC, a transmission method with the properties of massive connectivity, low peak-to-average power ratio (PAPR), and low out-of-subband emission (OSBE) is essential. Thus, we study on the integration of non-orthogonal multiple access (NOMA) and 5G new waveform. In this thesis, the integration of sparse code multiple access (SCMA) and circularly pulse-shaped precoding orthogonal frequency division multiplexing (CPS-OFDM) is proposed for 5G mMTC scenario. To integrate SCMA with CPS-OFDM, SCMA codebook design criterion are proposed and the SCMA codebook is designed. The physical-layer properties of low OSBE and low PAPR claimed by CPS-OFDM can be well preserved with the proposed SCMA codebook. Simulation results show that the proposed transmission method has better bit-error rate (BER) performance and spectral efficiency compared to other existing SCMA-OFDM-based schemes. | en |
