Implementation of Digital Communication Laboratory on FPGA

Abstract: This paper presents a method to describe all modulation techniques (like: BPSK, ASK, FSK, QPSK, QAM) on Field Programmable Gate Array (FPGA) development board which is widely available and inexpensive. To develop the system blocks Simulink environment and system generator version 13.1 are used under MATLAB version 7.11 (R2010B). To achieve simulation and synthesis of Spartan 3 FPGA tools from Xilinx ISE 13.1 are used. Very High Speed integrated circuit hardware description language (VHDL) is used for describing the hardware in system understanding language. Digital to Analog converter is used to interface both FPGA and CRO which is used to visualize the analog output of the digitally modulated signal.
