Optimized configurable architecture of modulation techniques for SDR applications

A software defined radio (SDR) is a device in which the functionality can be altered with the help of software. Hence defining the difference in behavior for various technologies in software, removes the need for hardware alterations during a technology upgrade. The role of modulation techniques in an SDR is very crucial since modulation techniques define the core part for any wireless technology. Implementation of modulation techniques with the approach of optimizing the architecture, implemented on FPGA and MATLAB, finally helps in reducing the architecture of SDR. The paper describes modulation techniques FSK and QPSK when configured together yields max optimization with good features.
