Space - time multiuser detection for ds - cdma communication in multiple input multiple output systems 直接序列碼分多址的多輸入多輸出系統(tǒng)中的空時(shí)多用戶檢測(cè)
In the severe interference environment of electronic warfare , it is important to suppress interference for reliability of information transmission . how to approach the capacity of distributed multiple input multiple output system is the key technique in beyond 3g 在電子戰(zhàn)的惡劣環(huán)境中,如何有效的抑制干擾是克敵制勝的前提;在分布式多輸入多輸出系統(tǒng)中,如何逼近其系統(tǒng)容量是下一代移動(dòng)通信系統(tǒng)的關(guān)鍵技術(shù)。
Iterative processing technique which is a nonlinear technique for joint signal processing by the means of exchanging prior information can approach better performance than traditional receiver , so this thesis introduces the research of iterative detection in anti - jamming communication system and distributed multiple input multiple output system 迭代檢測(cè)技術(shù)通過(guò)交換信號(hào)先驗(yàn)信息,將原本獨(dú)立的信號(hào)處理模塊聯(lián)系起來(lái),使系統(tǒng)獲得更優(yōu)越的性能。因此,本文圍繞著迭代檢測(cè)技術(shù)在抗干擾系統(tǒng)和分布式多輸入多輸出系統(tǒng)中的應(yīng)用進(jìn)行了研究。
