“…In fact, the field of application depends on the platform's capabilities. For example, the very low-cost RTL-SDRs are suitable for hobby and test below 1766 MHz [1,10,11], and the USRP platforms for cellular networks [24], and agile communication systems [25]. The software part is either open source or commercial.…”

The software-defined radio (SDR) is a flexible platform that can adapt to various wireless telecommunication frequencies. It is able to provide a reconfigurable communication infrastructure for wireless systems. Hence, SDR is proposed here as a bridge between legacy wireless communication systems and the Internet of Things (IoT) via standard telecommunication protocols. The standard protocols are hypertext transfer protocol (HTTP), simple mail transfer protocol (SMTP), and message queuing telemetry transport (MQTT). Data collected from legacy wireless systems have been formatted via JavaScript object notation (JSON) for interoperability and categorized according to the application and the communication pattern. The extracted data are then transferred over MQTT for machine-to-machine (M2M) communication, over SMTP for machine-to-human (M2H) notification, and over HTTP for human-to-machine (H2M) communication. However, received audio signals from FM-based broadcasting stations have been transferred to the Internet servers over extensible messaging and presence protocol (XMPP), in live audio streaming. The objective is to introduce an SDR-IoT bridge that is inexpensive, scalable, and interoperable. The analyses show that the environment has good-performance, and can be used for many applications of smart city sectors, for Internet Radio, and for Internet-based monitoring of airplanes and vessel navigation.

Software Defined Radio (SDR) is a new technology used to implement different wireless communication standard for mobile communication. The Intermediate Frequency (IF) block is the most demanding block in software defined radio. The most important task in intermediate processing block is digital filtering which is carried out by Finite Impulse Response (FIR) filter. One of the major techniques for the calculation of inner product is Distributed Arithmetic (DA) based FIR filter which uses Look Up Table (LUT) to eliminate the need of multiplier. The efficiency of the DA filter is affected with the increasing number of address line and also due to its serial operation. To overcome this problem parallel and pipeline based DA filter using Offset Binary Coding (OBC) for Two Bit At A Time (2-BAAT) is proposed. Our proposed method achieves less area, low power consumption and nominal delay for SDR application.
