FPGA implementation of CORDIC algorithm in digital modulation

Abstract

The modern communication systems and software radio based applications' demands fully digital receivers, consisting of only an antenna and a fully programmable circuit with digital modulators and demodulators.A basic communication system's transmitter mod amplitude, phase or frequency proportional to the signal being transmitted.This paper involves implementation of CORDIC (Coordinate Rotation Digital Computer) algorithm for generating digital modulation Amplitude shift keying (ASK) and Phase Sh CORDIC was introduced to implement and versatile algorithm widely used for digital signal processing application that works presented, the result obtained on Modelsim benefits of the proposed approach and implemented in DE applications.
