解讀 5G 八大關鍵技術 【摘要】5G 不是一次革命,5G 是 4G 的延續,我相信 5G 在核心網部分不會有太 大的變動,5G 的關鍵技術集中在無線部分。 在進入主題之前,我覺得首先應該弄清楚一個問題:為什么需要 5G?不是因 為通信工程師們突然想改變世界,而炮制了一個 5G。是因為先有了需求,才有了 5G。什么需求? 未來的網絡將會面對:1000 倍的數據容量增長,10 到 100 倍的無線設備連接, 10 到 100 倍的用戶速率需求,10 倍長的電池續航時間需求等等。坦白的講,4G 網絡無法滿足這些需求,所以 5G 就必須登場。 但是,5G 不是一次革命。5G 是 4G 的延續,我相信 5G 在核心網部分不會有 太大的變動,5G 的關鍵技術集中在無線部分。雖然 5G 最終將采用何種技術,目前 還沒有定論。不過,綜合各大高端論壇討論的焦點,我今天收集了 8 大關鍵技術。 當然,應該遠不止這些。 1.非正交多址接入技術 (Non-Orthogonal Multiple Access,NOMA) 我們知道 3G 采用直接序列碼分多址(Direct Sequence CDMA ,DS-CDMA) 技術,手機接收端使用 Rake 接收器,由于其非正交特性,就得使用快速功率控制 (Fast transmission power control ,TPC)來解決手機和小區之間的遠-近問題。 而 4G 網絡則采用正交頻分多址(
