Reconfigurable baseband modulator for software defined radio

Defining the hardware in terms of software is our main motto, In this era of wireless technology it is quite common for rapid change of technology and communication standards, As a result, when technology changes, changes in its circuit Architecture will takes place, so there is a need to design new architecture to use the new technology, In order to design, test and manufacture this new technology, it takes a countable amount of time, to overcome those issues J.Mitola has proposed a SDR concept [2]. Here we have providing a solution with system generator software, By which we can develop the required new hardware system very rapidly, and we can generate a required HDL code from the designed hardware system from system generator, The generated code we can dump into the FPGA to configure to the required technology. For this work we are using Spartan-3E on board xcs500e4fg320 device.
