AB  - BPSK and QPSK are two techniques for modulation are simulated in this paper employing VHDL and
Xilinx system software. Using VHDL to design the digital communications devices and implemented these
devices on FPGAs without arranging new hardware. Besides, it can be support new protocols within seconds.
Additionally, FPGAs provide a means for updating systems which are physically difficult to access, so, for
those reasons FPGAs offer an ideal platform to implement adaptive communications algorithms. In this research,
an approach is proposed digital modulator techniques which are comfortable for telemetry application and has
significant features such as simplifying the hardware design and significant high data rate. In this research, a
description is carried out for a method to implement the technique of modulation, BPSK and QPSK to transmit
high data rate by using VHDL, Field Programmable Gate Array (FPGA) is selected to implement the mentioned
technique. The proposed method is carried out successfully with VHDL language by using Xilinx ISE 10.2
design suite, SPARTAN-3FPGA also used to implement the previous technique.
