Obfuscation of Transmission Fingerprints for Secure Wireless Communications

Thursday, May 26, 2016

Marwan Krunz, Ph.D.

As we continue to depend on the rapidly expanding wireless ecosystem, we are challenged with threats related to user privacy, data confidentiality, and critical system availability. A significant portion of these threats is attributed to the broadcast nature of wireless transmissions. Using commodity radio hardware, unauthorized parties can easily eavesdrop on over-the-air transmissions and breach the privacy of communicating users by tracking their whereabouts and movements, and inferring their associations, health state, and preferences.

High-Efficiency Transmitters: The Road Ahead

Monday, May 2, 2016

Modern communication systems are rapidly increasing in complexity fueled by high customer demand for data-rich media streaming over the airwaves. With limited, and sometimes fragmented, available spectrum, very complex modulation schemes with relatively high signal bandwidth are used to be able to “pack” such high data contents for wireless streaming. As a result, tremendous pressure is now put on RFIC designers to deliver circuits that can handle such complex modulation and maintain the required high signal integrity while still be power efficient.

Wireless Systems that Extend Our Senses: Seeing Through Walls, Gesture Control, and Vital Sign Monitoring

Thursday, March 10, 2016

Fadel Adib, MIT

Wireless networks have been traditionally used for communications. However, wireless signals also have the potential to extend our senses, enabling us to see moving objects through walls and behind closed doors. Specifically, as these signals travel in the medium, they traverse occlusions and bounce off different objects before arriving at a receiver; hence, they carry information about the environment. The key challenge in extracting this information is that we live in a sea of waves which interact with each other and with the environment in complex ways.

Hello from the Director

Director Sujit Dey

Hello from the Center for Wireless Communications at UC San Diego, home of the annual 5G Wireless Forum and the newly created Connected Health Workshop.

As wireless communications continue to grow and evolve, it is essential that our mission and membership at the CWC grow and evolve in parallel. It therefore gives me great pleasure to announce we have welcomed several new companies as our members in the past year, including Kaiser Permanente, KETI, Samsung Research America, Murata and Teradata Labs. These new partnerships have been carefully selected to reflect several growth areas in wireless applications, from traditional wireless companies to data analytics and healthcare.
