Multiuser detection algorithm for ultra wideband multiple access communication systems 多址通信系統(tǒng)多用戶檢測(cè)算法
Spread spectrum technique is brought forward originally in military communication for antijam and low probability of intercept . it ' s capability in security and antijam makes its expensive applications in the fields of communication and detection . application in multiple access communication techniques accelerates nowadays - 3g technique 擴(kuò)頻技術(shù)最早是在軍事通信中為了抗干擾和降低截獲概率而提出來的,它的保密、抗干擾性能使它在通信和探測(cè)領(lǐng)域得到廣泛的應(yīng)用,擴(kuò)頻技術(shù)應(yīng)用于多址通信(碼分多址)使得當(dāng)今的移動(dòng)通信和3g通信等技術(shù)得以快速蓬勃的發(fā)展。
Multi - uesr detection ( mud ) refers to signal detection in multiple access communications . this detection has many good properties , such as decreasing multiple access interference , canceling out or moderating near - far resistance , able to decrease the requirement for output control , compensating the effects due to inoptimal orthogonality , improving system performance and increasing system capacity . mud is one of the methods that can overcome the mai in cdma with most potential and complete and becomes one of the critical techniques in the third generation mobile communication 多用戶檢測(cè)是指多址通信中的信號(hào)檢測(cè),具有抑止多址干擾;消除或減輕遠(yuǎn)近效應(yīng);可適當(dāng)降低對(duì)功率控制的要求;彌補(bǔ)擴(kuò)頻碼互相關(guān)性不理想造成的影響;改善系統(tǒng)性能,提高系統(tǒng)容量等眾多優(yōu)點(diǎn),是克服cdma多址干擾最有潛力、最徹底的一種方法,并已成為第三代移動(dòng)通信標(biāo)準(zhǔn)中倡導(dǎo)的關(guān)鍵技術(shù)之一。
