Next-Generation Mobile Software Defined Radio

The U.S. military’s next-generation radio system, Joint Tactical Radio System (JTRS), is based on Software Defined Radio (SDR) technology and will create new opportunities, methods, and applications for generating and sharing tactical data. One of the many challenges in realizing the JTRS vision is to create small, lightweight, embeddable devices that operate from battery power, meet the requirements for performance, SCA compliance, and can be carried, worn, or embedded for mobile applications. DataSoft will identify the most promising available approaches for the development of low-cost embeddable software defined radios (SDR) that minimize power consumption and maximize battery life. This will be accomplished through the quantified evaluation of current and future SDR components and technologies. Our Phase I activities will develop a SDR architecture which incorporates available best-of-breed technologies from both commercial and Government sectors to produce an embeddable low-cost, small size and weight, low power consumption SDR device composed of commercially available components, that can take advantage of the JTRS software communications architecture (SCA) and software waveform library.
