Implementation of Multiband Communication Using SDR for Remote Application

To develop Next Generation Wireless Communication a generic hardware design is required so that it can be driven by software to allow for future upgrades. Thus Reconfigurable Radio implements multi-band, multi-mode operation and interoperability with low-cost. For reducing response time between incompatible radios during emergencies interoperability is essential for a secure heterogeneous communication. Some of the Challenges identified for implementing reliable and reconfigurable wireless communication systems are: specific training required for using the equipment, end-to-end connectivity between devices, extending link capacity during the high peak utilization. Each device and architecture will differ based on the type of communication system. Interconnecting emerging fields enhances the performance , implementation helps to come across alternatives to overcome practical difficulties and challenges of connecting different fields to Cognitive Radio(CR). Earlier research gave prominence to theoretical and simulation-based work. This motivates us to verify interoperability in real time using SDR. This paper describes the implementation of a Multiband, multimode operation for establishing communication between different types of architecture i.e. VUSDR (HAM), Hack RF One, LoRa, RF module, GSM module and USRP N210 to prove reliability and end-to-end communication.

A Reconfigurable Radio-Frequency Converter IC in 0.18 µm CMOS

This work presents a reconfigurable RF converter for DVB-T television applications using triple-play over GPON. The system takes the DVB-T input, a wavelength division multiplexing (WDM) signal with spectral inversion in the range from 47 M Hz –1000 M Hz , up-converts its frequency to the band-pass of a highly selective surface-acoustic wave (SAW) filter centered at 1 . 3 G Hz , and then down-converts it so that it is compatible with the antenna input of conventional television sets. The designed RF converter incorporates two pairs of frequency synthesizer and mixer, based, respectively, on an integer-N phase-locked loop (PLL) with two LC-tank VCOs with 128 coarse tuning bands in the range from 1.35 G Hz –2.7 G Hz , and a double-balanced Gilbert cell, modified for better impedance matching and improved linearity. It is fed with regulated supplies compensated in temperature and programmed by an I 2 C interface operating on five 16-bit registers. This work presents the experimental characterization of the whole system plus selected cells for stand-alone testing, which have been fabricated in a 0 . 18 m CMOS process.

Design and Implementation of Frequency Reconfigurable Microstrip Patch

In this paper, radio wire recurrence reconfiguration is finished utilizing a proficient method. Traditional radio wires work at a specific recurrence run henceforth it is intended for explicit application and we can't work it on different frequencies. This proposed radio wire is equipped for changing to two distinct frequencies of 2.4 GHz and 2.754 GHz. Stick diode MA4P274-1141T has been presented on the ground plane. Stick diode which can switch among two diverse recurrence groups. The anticipated recieving wire has been planned utilizing RT/Duroid substrate with a relative dielectric steady of 2.2, misfortune digression of 0.0009 and thickness of 1.575 mm. Contrasted with regular recieving wires, reconfigurable radio wires talked about in this paper work at two distinctive recurrence ranges and furthermore it improves the exhibition. In this paper a smaller recurrence reconfigurable microstrip fix recieving wire has been given less return misfortune and high gain in contrast and the customary one. HFSS programming is utilized for reenactment and examination
