conventional detector meaning in Chinese
普通探测器
Examples
- For inevitable interference and error under complex ambient backgrounds , conventional detectors for weak signals will not work well
在信号检测尤其是微弱信号和复杂背景环境下的信号检测,常规检测器的效果不尽如意。 - Conventional detector ( single - user matched filter ) distinguishes each user by the crosscorrelation of their spread - spectrum codes . in practice , however , its performance is much deteriorated due to the existence of noise in channel and strong multi - access interference , i . e . near for effect . a new method using independent component analysis is proposed in this paper . the - received energy of signals is controlled effectively , thus the near - far effect is overcome as much as possible ; moreover , the effect that noise imposed on the detector is mostly reduced . simulations verify the effectiveness of this method
传统检测器(单用户匹配滤波)利用扩频码之间的互相关特性来区分各用户信号.而在实际应用中,信道噪声和近距离用户对远距离用户的强多址干扰即远近效应,使得接收机的性能受到很大影响.本文将独立分量分析法引入传统接收机,有效控制接收信号的能量,从而极大地提高了接收机的抗远近性能,同时噪声的影响被尽可能消除.仿真结果表明了该方法的有效性和可行性 - The simulation results show that the proposed detections benefit greatly from the pso and have significant performance improvements over conventional detector ( cd ) and previous multiuser detectors based on genetic algorithm ( ga ) or evolution programming ( ep ) in terms of bit - error - rate and convergence rate
仿真结果表明,这种多用户检测器充分利用了粒子群优化算法的优良特性,与传统的码分多址接收机、基于进化算法的多用户检测器和基于遗传算法的多用户检测器比较,在误码率和收敛速度等方面都有显著的改善。 - Multiuser detector ( mud ) makes full use of the information of all the users that cause multiple access interference ( mai ) to detect the desired user . therefore , as compared with the conventional detector , it has better resistance capability to the mai and the so - called near - far problem . since the multi - user detector reduces the precision requirement of the power control , it can provide higher efficiency for frequency use , and thus improves the capacity of the communication system
多用户检测技术在传统检测技术的基础上,充分利用造成mai干扰的所有用户信号信息对单个用户的信号进行检测,从而具有优良的抗干扰性能,解决了远近效应问题,降低了系统对功率控制精度的要求,因而可以更加有效的利用频谱资源,显著提高系统容量。 - Conventional detectors , for example , inductive loop , detectors using ultrasonic , microwave , or infrared , have been put into use for several decades . meanwhile , a promising approach , video - based measurement system , has developed quickly . since it has many advantages , for instance , wider - area detection and superior flexibility , many researches have been done in this area
