In this paper, the authors design and implement a software defined radio based wireless communication system. Software defined radio is a feasible solution for reconfigurable radios, which can perform different functions at different times on the same hardware. The design of the transmission side of a SDR (Software Defined Radio) based on the use of specialized Digital Up Converters (DUC) where baseband processing is performed and up conversion to Intermediate Frequency (IF) is performed. Similarly in receiver side of digital communication Digital Down Converter (DDC) is used. QPSK is used as both modulation and demodulation techniques.
