Universal MIMO-OFDM SDR for Mobile Autonomous Networks

Agility, learning, and adaptability are three main elements for modern military communication systems. These systems must be capable of transparently "morphing" to support a multitude of modalities on a single platform by intelligently adapting to changing requirements such as environment variations and user specifications. Furthermore reliable communication of time-critical information in a robust jam-resistant communication network remains of utmost importance. Such an agile and cognitive wireless system is only possible with the innovative integration of state of the art techniques such as MIMO and OFDM in a highly advanced SDR framework. This versatility is enhanced by combining a programmable RF front-end, digital IF sampling and controllable spectrum selectively via direct digital frequency synthesis (DDFS) to provide an unprecedented degree of carrier frequency agility. Finally, the system must be outfitted with cognitive and cataloguing algorithms to allow it to autonomously learn and adapt to changing radio environments, changing terrain conditions, changing network topology, and changing QoS requirements. Pulsar Communications is uniquely poised to leverage the extensive wireless experience existing within its staff to develop a universal MIMO-OFDM SDR platform for mobile autonomous networks.
