In this paper the varieties of anti-jamming margin about the two despread techniques in different environment are analysed,and simulation is made by MATLAB tool in accordance with the actual engineering system.

BPSK直擴(kuò)通信系統(tǒng)具有相干和異步相關(guān)兩種解擴(kuò)體制,工程上對兩種解擴(kuò)體制抗干擾能力估計(jì)易相互混淆,為此,分析了這兩種體制在不同干擾環(huán)境中抗干擾余量的變化規(guī)律,并采用MATLAB仿真工具按照實(shí)際工程系統(tǒng)建模仿真,從處理增益和譯碼門限等方面論述了不同解擴(kuò)方式下抗干擾余量的差異及其計(jì)算方法,結(jié)論可為相關(guān)工程的指標(biāo)分配提供參考。

Especially for the load factor,interference margin analysis,this article gives the situation of different cell load uplink budget.

特別是對負(fù)荷因子、干擾余量進(jìn)行了分析,給出了不同小區(qū)負(fù)荷情況的上行鏈路預(yù)算舉例。

To overcome this shortcoming, a new method is proposed to describe the abnormal input voltages, and a concept of anti-disturbance vector is introduced and added to the rectifier modulation vector to improve the output waveforms.

針對常規(guī)空間矢量調(diào)制法不能抑制非對稱、畸變等非正常輸入電壓對雙級矩陣變換器輸出所產(chǎn)生的影響,對雙級矩陣變換器空間矢量調(diào)制策略進(jìn)行改進(jìn),提出一種新的非正常輸入電壓表示方法以及抗擾分量的概念,通過在整流調(diào)制矢量中引入抗擾分量來提高雙級矩陣變換器的輸出波形質(zhì)量。
