most intuitive tool for designing digital communication on FPGA (to be more specific: for DSP in digital communication) is Xilinx System Generator. It generates VHDL according to the model defined in simulink.
Also, the question of theoretical background (what exactly to implement) is more important than the question of how to implement?!?

There are PLL model in the simulink library.
Use it directly.

Is there anybody who have worked with simulink embedded target for BPSK demodulation. I want to know which embedded card to use, what are the steps of the applications.... I would be glad if you share your experiences in the subject.

I want to ask a question about the subject. Can we implement such a demodulation with DSPs? Is there a DSP card for this application (TI or Motorola)? I want to learn whether such a demodulation can be implemented on a DSP using simulink automatic code generation tool.

otherwise anyother simulation tool is available for this???
use simulink to get sine signal and you can use system generator implement Psk,fsk on xilinx FPGA.

Can you suggest me how can we demodulate the DQPSK signal in simulink, using the Xilinx blockset. I am implementing in FPGA, hence I need to use only the xilinx blockset.
Any pointers for the tutorial would be helpful as well.

It is very simple to implement BFSK De-modulator you have to make two filters and diode detectors. What you can do implement the design on simulink and generate its code.

You can use IP cores that are developed for FPGA implementation. Many companies offer such IP cores for the wireless and telecommunication application domain. For example, you can use Xilinx SystemGenerator to generate a netlist for FPGA implementation from a model specified by using Matlab/simulink.

I have created a model using simulink simulating what you have stated but not the antenna.
what i suggest is that you choose a system (wi-fi, DVB, etc...) and look into the standard and start creating your model.

You can use matlab simulink.
There are already blocks for many modulation techniques
you can build up your modulator manually.
