band noise meaning in English
带噪音
频带噪声
Examples
- Testing hearing aids with a broad - band noise signal
助听器的宽带噪音信号测试 - In - band noise
带内躁声 - Based on the analysis and study of the primary principle and countermeasure process of the underwater acoustic countermeasure equipments , the mathematical models of the typical underwater acoustic countermeasure equipments such as the wide - band noise jammer target radiation noise simulator echo simulator and the gas bubble are presented
在详细分析、研究水声对抗器材有关基本概念、基本工作原理及对抗过程的基础上，归纳、总结了噪声干扰器、目标辐射噪声模拟器、主动回波模拟器及气幕弹等当前典型水声对抗器材的数学模型。 - Then , this paper presents a fast time - delay estimation algorithm ficp ( fine interpolation of correlation peak ) . this algorithm can effectively reduce the impact of signal non - stationary and improve the accuracy of tde ( time - delay estimation ) without increasing calculating complexity . what ' s more , it can reduce the interference caused by wide band noise
为降低信号非平稳性的影响，提高时延估计的精度，文中提出了一种快速相关峰细化时延估计算法ficp ( pineinterpolationofcorrelationpeak ) ，此算法精度高，速度快，另外还可以抑制宽带噪声的影响。 - In this paper , bit - error rate performance analyses are presented for coded and un - coded frequency hopping m - ary frequency - shift keyed systems under the condition of additive white gaussian noise ( awgn ) and partial band noise jamming and multitone jamming . the use of error - correct codes provide a way to improve the performance of frequency hopping system , particularly the use of reed - solomon code in a fh system under the condition of partial band noise jamming can greatly improve the performance of system . so we provide the way of coding and decoding of rs code in c language . in the end , we offer the simulation of the performance of time diversity fh / 2fsk system over partial band jamming noise channels
