One solution to this problem lies in a new class of radio antennas that could dramatically reduce man - made interference 有一类新型的无线电天线可大幅减轻人为干扰,或许能解决这个问题。
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 目前已形成产品的曲柄连杆机构动平衡机虽然取得了良好的效果,但仍存在许多不足:效率低、精度不高、人为因素干扰大,调试困难。
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 论文研究了在强人为干扰和非周期扩频码情况下,基于mmse准则的扩频系统自适应天线阵的实现和应用问题,包括参考信号提取、自适应天线阵中的afc ,并给出了在非扩频信号单边带ssb ( singlesideband )信号通信系统中的自适应天线的应用。
