针对FH/MFSK系统,将宽带扫频干扰带宽最小分辨率精确到MFSK信号带宽的1/M,分别在忽略背景噪声和AWGN信道两种条件下,对系统的抗干扰性能进行了理论推导,给出了误比特率的闭合表达式,并对理论结果进行了仿真验证。结果表明,当干扰带宽越窄,干扰带宽最小分辨率对系统的误比特率结果影响越大;AWGN信道中,在干扰功率、带宽一...

The jamming robustness of frequency hopping (FH) systems with M-ary frequency shift keying (MFSK) modulation may be potentially neutralized by a follower partial-band jammer. In this paper, a maximum likelihood (ML)-based algorithm that uses a two-element array is proposed for joint follower ja...
a kind of tone fast-hop-collision jamming model,analyzes the jamming performance of FH/MFSK system,and simulates the bit error ratio performance of FH/MFSK system under the fast-hop-collision jamming.The simulation result shows that the tone fast-hop-collision jamming can threaten the FH system...

【#警惕假消防培训实为高价带货#】近期,在一些学校微信群,某些人员自称消防专家、消防工作人员在线进行消防安全培训,以“恐吓式”讲课,变相逼迫家长购买消防器材,一块几十块的家用灭火毯卖几百块。提醒:凡是推销消防器材的培训、上门收取费用的培训、以培训为名接洽消防工程的都是“假培训”! L北京通州消防的微博...
