Design and Implementation of Area Efficient BPSK and QPSK Modulators Based On FPGA
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
Digital communications devices designed on FPGAs are capable of affording multiple communications protocols without the need to arrange new hardware, and can support new protocols in a matter of seconds. In addition, FPGAs provide a means to update systems that are physical difficult to access. For these reasons, FPGAs provide us with an ideal platform for implementing adaptive communications algorithms. This paper proposes a new approach to digital modulator techniques, applied to telemetry applications; simplifying the hardware design and inherently increasing data rate. This paper describes a method to implement modulation techniques (BPSK, QPSK and 8PSK) to transfer high data rate on field programmable gate array (FPGA). The implementation have been successfully done in VHDL using Xilinx ISE 13.2 Design suite and finally implemented in SPARTAN-3 FPGA.
