Design and simulation of Software Defined Radio using MATLAB® SIMULINK®

Software Defined Radio (SDR) has been one of the new techniques developed to change the way the traditional wireless communication systems work. SDRs enable us to build reconfigurable and interoperable radios that can be upgraded for future technologies. Designing a multi-modulation schemes system in term of hardware will cost a lot and definitely consume power and increase the interference. This paper presents the design of baseband processing section of Software Defined Radio, using MATLAB® SIMULINK® tool incorporated with Xilinx System Generator, using QPSK. The simulated results of designed SDR system are verified through hardware co simulated results. The same model is then in its Verilog form synthesized in Xilinx ISE Design suite.
