چکیده (انگلیسی):

Software Defined Radio (SDR) technology enables wireless
devices deployment with support to multiple interfaces in modulation
formats and it has gained importance due to the current wireless standards
proliferation. In order to activate these functionalities it is necessary to
apply SDR inside a reconfigurable hardware such as the Field
Programmable Gate Array (FPGA). In this study, design procedures
developments are presented resulting in a Quadrature Phase Shift Keying
(QPSK) modulator/demodulator based on a hardware architecture of the
Xilinx FPGA Zynq family. Also in the modem’s conception it was
employed the Xilinx Vivado-tool combined with Matlab, Simulink and
development with ISE/EDK apparatuses. As for the reconfigurable
hardware platform applied to this, it was utilized the ZedBoard along with
the Analog Devices FMCCOMMS1 radio module. In addition, it is
noteworthy to indicate that the entire software-hardware solution was
initially carried out through a simulation that achieved the system scheme,
including the hardware platform, before any hard implementation of the
QPSK modem itself. The central goal in this investigation is to fully
demonstrate how to construct a feasible radio system through software as
close to the state of the art as possible.
