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(duì)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(mén)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(duì)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.
