FPGA-Based Software-Defined Radio and Its Real-Time Implementation Using NI-USRP

Abstract

In this chapter, we propose a novel design of scalable and real-time data acquisition software architecture for software-defined radio (SDR) using universal software radio peripheral (USRP). The software has been designed and tested in multi-thread model, using LabVIEW, which guarantees real-time performance and efficiency. With the help of this design, we have been able to improve the stability of the system besides providing a reconfigurable and flexible architecture. Wireless transfer of sensitive data using communication is not a very safe option. In this chapter, we aim to provide a safe and private wireless transmission between two terminals using the SDR approach and verifying the results in real-world environment with the use of USRP. The novel design being presented here can be used to transfer (random data, text or an image) encoded with different forward error correction (FEC) codes, which is then verified at the receiving terminal and then decoded accordingly to produce the desired result.

Range Evaluation of a Point-to-point Link using Software Defined Radio

“…However, as a disadvantage derived from their versatility, these systems are relatively complex in software or firmware design, since advanced knowledge of communication techniques, current regulations about the band to be used, and intensive use of advanced devices such as FPGA is required.
