i would like to use this method ...can u suggest me the right fpga that i can use....

The paper indicates the carrier and data rate:

"rectangular waveform with frequency of 140 KHz which is much greater than the used data baud rate (500 bit/s)"

So literally any FPGA can be used.

and few tutorials sites where i can learn on writing verilog coding for this applications

Use Google. Use the tutorials that come with Modelsim, Quartus, and the University program code.
