The anti-noise amplitude modulation(AM) spot jamming performance of pseudo-random code phase modulation fuze,pseudo-random code phase modulation and pulse amplitude modulation(PAM) combined fuze,and pseudo-random code phase modulation and pseudo-random pulse position modulation(PPM) combined fuze is researched based on the criterion of signal to jamming ratio(SJR) gain.
该文以信干比增益作为衡量标准来研究伪码调相引信、伪码调相与脉冲幅度调制(PAM)复合引信、伪码调相与伪随机脉冲位置调制(PPM)复合引信的抗瞄准式噪声调幅干扰性能。
3) noise AM-FN jamming
噪声调幅调频干扰
4) Noise AM-PM jamming
噪声调幅调相干扰
5) Amplitude noise
振幅噪声
6) clipping noise
限幅噪声
1.
Firstly, the algorithm uses PTS to process OFDM signal to select the smallest clipping noise of OFDM signal, then the algorithm uses clipping to process OFDM signal, so the algorithm can reduce the clipping noise that caused by clipping and better reduce the impact of clipping for OFDM system.
该算法先利用PTS算法对OFDM信号进行处理从而选择出限幅噪声最小的一路OFDM信号,所得OFDM信号再利用限幅法进行处理。
补充资料：调幅
载波振幅按调制信号振幅而变化的调制方式。载波经调幅后成为调幅波。调幅波的最大与最小振幅之差的一半与其和的一半之百分比称为“调幅度”。
