摘要

摘要:
在进行扩频系统设计时，有时需要分析系统的抗干扰能力，但现有的文献中关于直接序列扩频系统的抗宽带干扰能力、抗部分频带干扰能力说法不一致，提供的误比特率(BER)公式也互相不一致。该文通过理论推导给出了直接序列扩频系统在宽带干扰、部分频带干扰下更具一般意义的误比特率公式，并通过计算机仿真验证了该公式的正确性。最后利用该文给出的公式对直扩系统的性能随干扰频点、干扰带宽的变化趋势做了分析。

Abstract:
When designing a spread spectrum system, it is sometimes necessary to analyze the anti-interference ability of the system. However, the existing literature on the anti-wideband interference capability and the ability to resist partial frequency band interference of the Direct Sequence Spread Spectrum (DSSS) system are different, and the Bit Error Rate (BER) formulas provided are different, the general BER formula of direct sequence spread spectrum system under wideband interference and partial frequency band interference is given by theoretical derivation. The correctness of the formula is verified by computer simulation. Finally, the performance of the DSSS system with the interference frequency and the interference bandwidth is analyzed using the formula given in this paper.
