“…The jamming signal phase as also noise signal phase in relation to the RCIED activation signal directly follow from the uniformly distributed random number. Amplitudes of noise signals are calculated starting from the uniformly distributed random numbers, which are modified using the Box-Müller method [29]. The simulation is performed for the variable values according to the example from Section V, including JR=0.63.…”

This paper presents a new method for jamming of GSM communications. The aim is to decrease voice connection quality, thus disabling users to understand each other, while keeping established connections. The jamming method parameters depend on the algorithm characteristics implemented in SACCH frame. It is proved for three mobile telephony codecs that it is possible to reach unsatisfactory voice connection quality MOS<2 due to jamming of a GSM communications channel. Errors in data transmission during the periods without jamming also cause voice connection quality impairment and this influence is analyzed. The method performances are compared to other solutions.

“…The uniform discrete spectrum components in this case are modified (multiplied) according to the law (sin(x)/x) 2 , as obvious from (12). This means that necessary jamming signal power has to be higher than if the frequency spectrum is completely uniform.…”

“…As now the amplitude of the frequency component at k=3 (which has the lowest level of the considered components) is relatively higher comparing to the component at k=0, it may be concluded that it is important to implement as short as possible impulses duration τ. But, due to the effect of the multiplication factor τ/T in (12), the absolute value of the frequency components amplitudes is decreased. It is necessary to compensate the effect of this attenuation by the greater pulse amplitude A (higher signal amplification in the method realization).…”

The characteristics of combined and comb jamming of RCIED activation messages are presented in this paper. Combined jamming signal is formed as the sum of swept sinusoidal signal and noise signal, while comb jamming signal means that its spectrum has a number of simultaneous discrete equally distant sinusoidal components, eventually further swept. The performances of combined jamming are compared to pure sweep and pure barrage jamming. They are determined on the base of originally developed simulation program implementation. Comb jamming is analyzed based on its generation from rectangular pulse train. It is presented how the selection of ratio of pulse duration to its period and the number of frequency components in comb signal influence the obtained jamming signal characteristics. It is proved that comb jamming is especially advantageous in relation to sweep jamming when RCIED activation message duration is significantly lower than the sweep cycle period.
