Research on Noise Suppression Performance of High-Speed Broadband FH Communication System Based on MSK

FH(frequency hopping) is widely concerned in the field of communication because of its outstanding ability of noise suppression. The suppression ability of FH communication can be improved by increasing the bandwidth and hopping rate. MSK is chosen as a modulation of high-speed broadband FH communication system to research the suppression ability of FH to different noise signals. The diagram between ratio peak and ISR (interference-signal power) can be given in different bandwidths and different hopping rates. It is verified that the broadband high-speed FH communication system with MSK as the modulation mode has not only a smaller BER (bit error rate) but also a higher noise suppression.
