VLSI Implementation and Design of Digital Modulation Using Xilinx
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 9
Abstract
In this Paper, Digital Modulators is designed and Implemented using XILINX ISE Tool based on Very Large Scale Integration (VLSI). This is majorly to implement and obtain digitalize signals in softwaredefined radio (SDR) for signal power. SDR is a very widespread solution, whose modulation / demodulation methodology consists in programming the software in a dedicated programmable logic device (FPGA). This results in a high degree of versatility in the equipment because the same physical hardware can be used to implement different digital modulators / demodulators. In this context, Field-programmable gate-arrays (FPGA’s) are the best solution, due to their best performance. Using XILINX software tools, the digital modulators schematic and simulations are designed and are presented, which helps to obtain accurate design constraints. As part of this we have integrated into Fieldprogrammable gate-array (FPGA) with the help of VERILOG Hardware Description Language (net-list). Here by using Spartan 3E the implementation is done and the results are observed.
