 24 Sep 2008 13:04 Project Implementation in Matlab Simulink. |

I'm implementing Dual band cell phone jammer in Mtlab Simulink,,,but i'm facing problem in VCO and buffer,,,how to adjust thier parameters according to the requirement,,,plz help me.
Project detail is:
I will jam two GSM bands i.e; GSM 900 & GSM 1800.
It will cosists of two parts:
1)IF section
2)RF section
In the IF section following components will made;
a)Triangular wave generator (Sweep generator)
b)Noise generator
c)Mixer
d)Clamper
RF section contains following parts:
a)Two VCOs(output frequencies equal to downlink frequencies of the bands).
b)The power amplifier;
This jamming techniques is DENIAL of SERVICE:
In this technique, the device transmits a noise signal at the
same operating frequency of the mobile phone in order to decrease the signal-to-noise ratio
(SNR) of the mobile under its minimum value. This kind of jamming technique is the
simplest one since the device is always on.
