Frequency-hopping communication is an effective technique for anti-interference, which has significant application value and vast development in such fields as military communication, mobile communication, wireless local area network and wireless personal communication. This article demonstrates the influence of several common man-made interferences on frequency-hopping system capacity and stresses the research on anti-interference capacity against some frequency bands. Based on simulation experiment, this article comes up with the improvement for frequency-hopping system in light of frequency diversity technique. The experiment shows that the improved frequency-hopping system’s anti-interference capacity against some frequency bands has increased greatly.
