This thesis presents a Software Defined Radio (SDR) which proves a great solution to develop a radio communication process through software. The greatest advantage of SDR is it avoids the hardware and replaces with the software which provides great flexibility to decode all different types of radio signal. Here we proposes a new six-port integrated waveguide structure and our simulation results proves a great flexibility and robustness in system configuration and software reuse of data processing by using quadrature shift keying and 16 quadrature amplitude modulation schemes. This paper presents a universal demodulator for several wireless communications.
