摘要
针对无线信道中的高斯白噪声、窄带干扰问题,采用重叠变换的FFT频域陷波算法对相关干扰进行削弱或消除,并将其在扩频通信系统中进行了仿真分析。结果表明,这项技术可使受干扰后的频谱泄露大大降低,从而减少了信号的损伤,提高了信息传输的准确性、可靠性。
For interference of Gaussian white noise and narrowband in wireless channel, overlap conversion FFT frequency domain notch filter algorithms can be adopted to reduce or eliminate relevant interference. Simulation analysis can be conducted in upon it in spread spectrum commu- nication system. Results show that the technology can greatly reduced the interference spectrum leak and the signal damage and it improves the accuracy and reliability of information transmission.
