Trans-receiver with digital modulator & frequency up converter for secured communication

Abstract

Trans-receiver designed with programmable digital Modulators, Frequency up converter, RF Tuner & Digital demodulator can be used for secured communication. The proposed system will be useful for frequency Trans-modulation applications also for the frequency range of 50 MHz to 2.5 GHz for various signal types like DVBC, DVBT, ISTBT, NTSC etc. Secured communication between the systems are required in many applications which can be achieved using the proposed system. Simple Trans-modulation technique is used for the frequency conversion. Programmable Modulator & RF frequency up converter are used as Transmitter whereas Tuner &programmable Demodulator will function as receiver. The designed system is useful for any commercial or military applications.
