Due to its reconfigurable ability and high throughput performance, Field Programmable Gate Array (FPGA) is widely used in embedded applications such as automotive, communication, industrial automation, motor control, medical imaging, to name a few. In this study, a reconfigurable communication system using Quadrature Phase Shift Keying (QPSK) modulation is to be designed and implemented on an FPGA. Some building blocks of digital communication systems were implemented using MATLAB/Simulink. The major drawback of Simulink-based tool is that the logic resource usage highly depends on the software automation and, thus the design may not be compatible with different versions of software. Hardware description languages (HDL) such as VHDL and Verilog HDL require much experience in digital system design and programming. HDL, however, can provide an efficient solution in terms of logic resource usage and design compatibility. The goal of this study is to implement a complete QPSK system on FPGA boards using VHDL. The project aims to build a QPSK communication system whose building blocks are reusable and reconfigurable.Preliminary results will be presented.
