Both the LUT based implementation and complete VHDL based implementations have done by using digital high frequency carriers. In the first step to realize the whole modulation and demodulation schemes using MATLAB Simulink. The format of a VHDL program is built around the concept of BLOCKS which are the basic building units of a VHDL design.
