In this paper, the authors describe the hardware design and implementation of an inexpensive Software Defined Radio (SDR). SDRs use a hardware front end but can change their operational frequency, bandwidth requirement and various standards by implementing various software algorithms. Rather than using analog blocks for design of radios, as is the convention, this paper details the use of digital signal processing for implementation of radio system. Such a solution provides inexpensive, efficient interoperability between frequencies and standards.
