| 摘 要： | 研究了DS(direct sequence)扩频系统中基于隐藏马尔可夫模型HMM(hide Markov models)的干扰抑制技术，简要引述了算法原理，着重给出了该算法的改进方案和在具体干扰条件下的系统性能仿真。研究表明，该算法由于能够对干扰信号进行准确估计，因而减小了对有用信号的损伤，可以获得更好的抗干扰性能。通过减小复杂度的措施，可以用于实际系统，这对于应用DS扩频系统的短波通信和卫星通信，增强抗干扰能力具有重要意义。

| Abstract: | The narrow interference rejection based on HMM for DSSS system is studied. Principle of the algorithm was quoted, the adapted means for the algorithm were given and the performance simulations were done for special interference modes. Results showed the algorithm could reduce the loss of useful signal. By reducing implementation complexity the algorithm could be used in practical system. It is meaningful for short wave communication system and satellite communication system with DSSS technology. |
