The simulation of the system proves all the features mention above. They have designed the system using VHDL codes in Xilinx & analog filter simulation in Matlab.

Later on they have implemented a QPSK modulation technique using reversible logic and the QPSK modulator unit will be modelled using HDL code and simulation will be done by ModelSim 6.0 simulator ...
