One solution to this problem lies in a new class of radio antennas that could dramatically reduce man - made interference 有一類新型的無線電天線可大幅減輕人為干擾,或許能解決這個(gè)問題。
At present , some dynamic balancers are researched & developed and manufactured , and there are good effect , but there are still such many shortage as inefficiency , precision low , man - made interference greatness and debug difficulty 目前已形成產(chǎn)品的曲柄連桿機(jī)構(gòu)動(dòng)平衡機(jī)雖然取得了良好的效果,但仍存在許多不足:效率低、精度不高、人為因素干擾大,調(diào)試?yán)щy。
This thesis investigates the application and implementation of adaptive array based on mmse criteria in the presence of strong man - made interferences and aperiodic spread spectrum codes , including reference signal generating , afc in adaptive antennas array , and an application of adaptive antennas for a general non - spread spectrum signal , ssb ( single sideband ) communication system is presented . the thesis is outlined as follows 論文研究了在強(qiáng)人為干擾和非周期擴(kuò)頻碼情況下,基于mmse準(zhǔn)則的擴(kuò)頻系統(tǒng)自適應(yīng)天線陣的實(shí)現(xiàn)和應(yīng)用問題,包括參考信號提取、自適應(yīng)天線陣中的afc ,并給出了在非擴(kuò)頻信號單邊帶ssb ( singlesideband )信號通信系統(tǒng)中的自適應(yīng)天線的應(yīng)用。
