As wireless technology continues to grow, new intelligent systems will be needed to help organize, manage, and interact with the surrounding RF environment. Such systems are based on a cognitive radio, where a device can learn and adapt to its RF environment. Motion detection, cybersecurity and spectrum sharing are few examples of such applications. However, for widespread adoption of such systems to be feasible, they must be small, cost-effective, maintainable, and offer high performance with…

Cognitive radio universal software hardware
TLDR
The CRUSH platform, proposed, can implement FFTs at 100× improvement, and can perform a complete sensing cycle 10× faster than legacy SDRs for large FFT sizes that enable wideband sensing, and will enable advances in both protocol design and radio hardware.
Hardware Accelerated SDR Platform for Adaptive Air Interfaces
TLDR
A flexible and compact platform is proposed for on-the-fly composition of low-power adaptive air interfaces, based on hardware/software co-processing on a single chip, allowing high processing throughput, at a smaller form factor and reduced power consumption.

TLDR
A fully integrated wideband active Duplexing transceiver with baseband noise-cancelling duplexing LNAs with passive mixer-first architecture for in-band full duplex operation with concurrent reception and transmission in the same band or closely-spaced channels is presented.
A high performance GPU-based software-defined basestation
TLDR
A high performance GPU-based software-defined basestation based on an existing WARPLab SDR framework that can not only achieve less than 3ms latency and more than 50Mbps throughput for processing streaming frames in real-time, but also offer software- defined flexibility and scalability for supporting future wireless standards.
Demonstration and Analyses of Collaboration, Coexistence, and Interoperability of Cognitive Radio Platforms
TLDR
An over-the-air interoperability analysis of two different SDR architectures in the same frequency band, including an initial analysis of actual co-existence experiences involving primary users and secondary opportunistic spectrum users in a common frequency band is presented.
A 1.7 mW 11b 250 MS/s 2-Times Interleaved Fully Dynamic Pipelined SAR ADC in 40 nm Digital CMOS
TLDR
A 250 MS/s 2x interleaved 11 bit pipelined SAR ADC in 40 nm digital CMOS is presented to adjust the uncertain gain of the chosen residue amplifier and various other non-idealities.
Through-the-Wall Sensing of Personnel Using Passive Bistatic WiFi Radar at Standoff Distances
TLDR
The results presented show the first through-the-wall (TTW) detections of moving personnel using passive WiFi radar, and it is shown that a new interference suppression technique based on the CLEAN algorithm can improve the SIR by approximately 19 dB.
Analysis and Optimization of Direct-Conversion Receivers With 25% Duty-Cycle Current-Driven Passive Mixers
TLDR
It is revealed that with an intelligent sizing of the design parameters, the 25%-duty-cycle-mixer-based receiver is superior in terms of linearity, noise, and elimination of IQ crosstalk.
