A Software Defined Radio (SDR) is a reconfigurable radio, in which channel modulation waveforms are defined in software. In this paper Software Defined Radio (SDR) 4-bit QAM Modem for Gaussian Channel is implemented using  abVIEW software. LabVIEW is a graphical development environment with built-in functionality for simulation, data acquisition, instrument control, measurement analysis, and data presentation. The aim of this paper is to simulate SDR for next generation wireless communication having Gaussian channel and Adaptive Filter is used to remove Gaussian noise present in received signal and minimize the effect of Intersymbol Interference. It is obvious from the Simulation results that SDR is suitable for Gaussian channel giving Optimum Performance.

LabVIEW is a graphical development environment with built-in functionality for simulation, data acquisition, instrument control, measurement analysis, and data presentation. The aim of this paper is to simulate SDR for next generation wireless communication having Gaussian channel and Adaptive Filter is used to remove Gaussian noise present in received signal and minimize the effect of Intersymbol Interference. It is obvious from the Simulation results that SDR is suitable for Gaussian channel giving Optimum Performance.
