Extensible Affordable Software Defined Radio with Cross-Band Cross-Protocol Capability

Currently developed and deployed communications systems, such as the Joint Tactical Radio System (JTRS,) already have the capability of providing multi-channel and multi-protocol high performance wireless communication. However, many of these systems have been delivered with high costs, high complexity, and with performance shortfalls, due primarily to immature technologies, unstable requirements, and aggressive schedules. As a solution to these problems, a scalable, low-cost, extensible, and expendable Software Defined Radio (SDR) platform is proposed. This platform will eventually support multiple platforms, waveforms, users, and radio standards. However, for our prototype design, a single-function, single channel communications device suitable for consumer use will be implemented, using commercial and in-house hardware and software technologies. For a future iteration, a more mature version of this inexpensive radio will be a high-performance multi-channel, multi-application system that will allow real-time “bridging” between legacy, current and emerging radio frequency communications standards and waveforms.
