Designing and Testing Software-Defined Radios

Software-defined radios (SDRs) will play a key role in future radio configurations because the emergence of new wireless technologies and their integration in a fourth generation of communication standards will necessitate the use of multistandard and multiband radios. SDRs use a single hardware front end but can change their frequency of operation, occupied bandwidth, and adherence to various wireless standards by calling various software algorithms. Such a solution allows inexpensive, efficient interoperability between the available standards and frequency bands.
