A Polyphase Multipath Technique for Software-Defined Radio Transmitters

Modulation Technique for Software Defined Radio Application

The role of radio in the communication systems have been extended from simple radio to mobile communications and beyond. Minimization or the replacement of hardware in communication technology through software has been resulted in the birth of a new technology, widely known as Software Defined Radio (SDR). This paper deals with the development of SDR to transfer information from one place to an...

A multipath polyphase digital-to-analog converter for software radio transmission systems

A digital-to-analog converter system compliant with the requirements of software radio transmission interfaces is presented. The system, through a proper combination of interpolation, digital filtering and data conversion allows us to relax the speed requirements of the analog and the digital section while fully satisfying the specifications. A design example and high level simulation results a...

Digital Synthesizers and Transmitters for Software Radio

Energy Detection Based Spectrum Sensing Technique for Software Defined Radio

A lot of hardware components are used to make a conventional radio communication system, the complexity of these hardware can be reduced with help of Software Defined Radio (SDR) which is a form of wireless communication. Software Defined Radio implemented system allows us to make alteration in it or operate it with help of a software, thus making the system flexible and reconfigurable. The sys...

Modular Software-Defined Radio

In view of the technical and commercial boundary conditions for software-defined radio (SDR), it is suggestive to reconsider the concept anew from an unconventional point of view. The organizational principles of signal processing (rather than the signal processing algorithms themselves) are the main focus of this work on modular software-defined radio. Modularity and flexibility are just two k...
