High Resolution Wide Band Direct Conversion Receiver

ABSTRACT: Rapid detection and analysis of signals over a wide frequency band in a dense signal environment continues to be an area requiring further research and development. Detecting low power time varying signals in the presence of strong interference over a wide frequency range in real time has proven to an elusive task. Advances in digital signal processing techniques and real time hardware implementation technology provide the basic tools for potentially realizing a receiver with the required dynamic range, resolution, bandwidth and flexibility to operate in a dense signal environment. RBS Technologies, LLC proposes to develop innovative signal processing algorithms and architectures for implementing a real time direct conversion receiver with the required resolution, bandwidth, and data processing/storage capability to operate in the projected dense signal environments. Emphasis will be placed on practical solutions that can be implemented in state of the digital processing hardware. BENEFIT: There is a broad range of applications in all branches of the military for a very wide band, high dynamic range direct conversion receiver for detection and analysis of RF signals. The commercial sector has similar requirements with wireless communications, global positioning systems (GPS), etc. operating in a dense signal environment with inadvertent or intentional interference.
