Multi-signal, software-defined and staring cognitive communications system

Abstract

The integrated, multiple independent, simultaneous signal software defined radio system architecture of this invention is suitable for many new very-low latency, software defined radio applications, both cognitive and conventional, including: communications networks, electronic warfare, surveillance and radar. The system supports multiple operations, locally controlled or remotely controlled, with simultaneous signals prosecutions and anti-jam system-to-system networking. New cognitive waveforms are defined that simultaneously seek to maximize data throughput in arbitrary spectral environments, while normally avoiding interference with current and new arbitrary signal occurrences. The cognitive radio system has the capability to continuously receive and process all the ongoing signals present in a wideband frequency block, including the recognition/characterization of all signals and the recovery of multiple desired signals, and then rapidly respond by transmitting as appropriate, multi-carrier, modulated signals. The present invention uses massively-parallel fixed tuned receive channelization, along with massively parallel digital signal processing and software generated, multi-modulated RF signals, to provide a system that is fast enough to cognitively manage the ongoing operation of multiple signals, multiple frequencies, and multiple operations, all simultaneously.
