Abstract |
|
CORDIC is nothing but COrdinate Rotation DIgital Computer. This is a versatile algorithm, widely used for VLSI implementation of digital signal processing (DSP) based communication systems. How to use CORDIC in satellite communication is explained in this paper. Specifically, Digital Down Converter (DDC), Direct Digital Frequency Synthesizer (DDFS), and use of CORDIC in digital modulator and demodulator has been explained. The algorithm and its applications are first realized on System Vue software tool and then designs are coded in VHDL. Apart from the implementation aspects, paper presents new results regarding the number of branches required for computation. The paper also analyzes the performance of CORDIC based DDC and DDFS on the basis of hardware requirement. The system is implemented on XILINX FPGA platform and tested in real time for its performance. |
