CBRS Sharing Ecosystem Assessment

Ongoing
Background: In 2020, FCC auction 105 auctioned licenses in the Citizens Broadband Radio Service (CBRS). CBRS (3.55 GHz to 3.7 GHz) has a three-tiered framework to accommodate shared federal and non-federal use of the band. The DoD 3.5 GHz Transition Plans focus on ecosystem validations

Characterizing User Equipment Emissions

Completed
Designed, demonstrated and validated a test methodology for measuring aggregate emissions over a wide range of condition. Several factors were evaluated, including the collective power distributions emitted by the UEs in a cell, the number of UEs transmitting simultaneously, the spectral properties

Citizens Broadband Radio Service

Ongoing
The FCC Part 96 rules establish a three-tier architecture for sharing the radiofrequency (RF) spectrum from 3550 MHz to 3700 MHz. Commercial users of the 3.5 GHz Citizens Broadband Radio Service (CBRS) band will share this spectrum with existing incumbents, including the federal government which

Classification of 3.5 GHz Spectrograms

Completed
This project compared various detection algorithms for federal incumbent radar signals in the 3550-3650 MHz band using a set of over 14,000 spectrograms collected by the completed Waveform Measurements of Radars Operating in the 3.5 GHz Band project. The results demonstrated that training deep

Cooperative Diversity Routing and Transmission for Wireless Sensor Networks

Completed
In order to address the challenges of cooperation, PHY layer cooperation schemes were proposed and, to a limited extent, medium access control (MAC) layer schemes. On the network layer, the network coding techniques can be viewed as a form of cooperation as well. To the best of our knowledge, there

Cooperative vs Non-Cooperative Diversity in Space, Time and Frequency
