在MATLAB進行5G NR實體層的建模、模擬與測試

演講摘要

本段演講將展示5G工具箱(5G Toolbox™)針對3GPP 5G New Radio (NR)實體層建模的應用。實現符合標準的MATLAB模型來探索5G實體層系統或元件的行為。這些示範將運用到MATLAB R2020a版本的最新功能。

技術焦點：

• 上行鏈路與下行鏈路的5G NR波形產生，包含預先定義(測試模型、FRCs)和完全客製的波形
• 混合彈性參數(numerology)、CP-OFDM、和SC-FDMA
• 建立5G上行鏈路與下行鏈路實體通道和訊號，如PDSCH/PUSCH、PDCCH/PUCCH、同步化突波(synchronization burst)、解調參考訊號(demodulation reference signals，DMRS)、CSI-RS、SRS、和PT-RS
• TR 38.901制定的通道模型，包含分接式延遲線(tapped delay line，TDL)和群聚延遲線(clustered delay line，CDL)
• 鏈路級模擬參考設計，讓你可以在2-D或3-D通道模型上測量下行(PDSCH)或上行(PUSCH)5G鏈路的吞吐量
• 同步化流程，包含細胞搜尋(cell search)和MIB解碼
• 毫米波(mmWave)的波束成形應用
• 下行鏈路ACLR量測

Model, Simulate, and Test 5G NR PHY in MATLAB

This presentation shows the application of 5G Toolbox™ for 3GPP 5G New Radio (NR) physical layer modeling. Standards-compliant models in MATLABR are implemented to explore the behavior of 5G physical layer systems or components. MATLAB version R2020a is used.

Highlights Include:

• Uplink and downlink 5G NR waveform generation including pre-defined (test models, FRCs) and full custom waveforms
• Mixed numerology, CP-OFDM, and SC-FDMA
• Modeling of 5G uplink and downlink physical channels and signals such as PDSCH/PUSCH, PDCCH/PUCCH, synchronization burst, DMRS (demodulation reference signals), CSI-RS, SRS, and PT-RS
• Channel models as specified in TR 38.901 including tapped delay line (TDL) and clustered delay line (CDL)
• Link-level simulation reference design, enabling you to measure throughput of a downlink (PDSCH) or an uplink (PUSCH) 5G link over 2-D or 3-D channel model
• Synchronization procedures including cell search and MIB decoding
• Beamforming applied to millimeter wave (mmw) transmission
• Downlink ACLR measurement
