Next Generation White Nail Architecture for Future Cognitive Radio Transmitter and Receiver Systems
Recent test results and future performance predictions for White Nail systems that provide a digital interface for wireless propagation Previous White Nail presentations have focused on the fundamental performance limits for developing digital images of wideband high dynamic range propagating RF signals and on the innovative evolution from those limits to the demonstration of new functionality that enables cognitive radio personality for signals intercept systems. In summary, the White Nail architecture is designed to exhibit adequate signal dynamic range for full-bandwidth operation of high-performance ADCs over frequency ranges greater than 20:1 and this performance is consistent with that predicted by the applicable fundamental limits.
This presentation will focus on two additional aspects of the White Nail architecture:
1) power efficient transmission of digitally synthesized waveforms and
2) a design for manufacturing that reduces the White Nail architecture to a highly simplified physical configuration.
1) Power efficient transmission results from the observation that the White Nail architecture can be configured to emulate a DAC with spatially combined VLSBs. Predicted DC to EIRP efficiencies greater than 80% can be substantiated by measured performance. A White Nail transmitter with EIRP > 10-kW can be configured using a basic 2-Watt amplifier designed for GSM hand-held phone applications that has a power added efficiency greater than 50%..
2) Design for open manufacturing is currently underway. The latest manufacturing design comprises a plurality of five distinct parts, each of which is configured for direct SolidWorks-to-CNC adaptation.
Only one part determines the signal functionality of the White Nail air interface and this part is designed to be manufactured to a specification that can be met by multiple vendors. Further, the part is designed to minimize development costs and to allow flexibility in setting performance objectives.
