Jamming Analysis of RF Noise with the Pectinate Spectrum on the Coherent Received FSK Signal

With the help of the several discrete frequency spots of FSK signal,the RF noise with the pectinate spectrum is proposed to jam FSK signals.And the detailed definition is done of the proposed jamming signal.The error rate formula of its effect on the communication receiver is deduced under the condition that the timing synchronization has been completed,in the case of 2FSK model.The theoretical analysis proves that the RF signal with the pectinate spectrum has the remarkable jamming effect on the reception and demodulation of communication signal.The conclusion is obtained that the RF noise with the pectinate spectrum has better jamming effect in comparison with the single-frequency jamming when the jammer is limited in power and the signal has larger power.And the simulation proves the correctness of theoretical analysis and the feasibility of actual application.
