使用FFT变换在频域对宽带扩频信号中的正弦干扰信号进行识别和抑制，其中扩频信号由1024点的伪随机序列表示。(In the frequency domain using the FFT transform of broadband spread-spectrum signal of sinusoidal interference signal identification and suppression, in which spread-spectrum signal is generated by pseudo-random sequence of 1024 points, said.)

说明：  this is the simple code for a beginner matlab programming to make a plot, change the plot color, change the dot shape etc.

matlab程序，高阶谱分析，信号谱分析的方法一起就存在了，高价谱分析是当代信号处理的主要工具。(Matlab procedures, higher order spectral analysis, signal spectral analysis method in existence, high spectral analysis of contemporary signal processing major tools.)

CSMA/CD(1-persistent): 当有packet需要发送时： • 如检测到信道空闲，发送packet • 如检测到信道忙，一直检测信道状态，一旦信道空闲，立即发送(CSMA/CD (1-persistent): When there is packet needs to be sent when: • If the channel is detected idle, transmit packet • If the channel is detected busy channel state has been detected, once the channel is idle, transmit immediately)
