The Next Silicon Revolution


The next silicon revolution is underway, and electrical engineers from the Jacobs School (pictured above) are in the thick of things.


"On-demand video delivered wirelessly is a tidal wave that is sweeping through communications networks on a worldwide basis, and it creates tremendous technical challenges at all layers of the network,” said Lawrence Larson, Professor and Chair, Department of Electrical and Computer Engineering (ECE) at the UC San Diego Jacobs School of Engineering. “In order to accommodate this soaring demand, wireless communications devices will have to operate at higher frequencies and wider bandwidths in order to supply the data. Visualize the link between the cell phone tower and your smartphone as a straw. That only lets a limited amount of data through at any one time. In the next few years, we are trying to turn the straw into a fire hose.”


And research into just how to turn a straw into a fire hose led to 23 accepted UCSD papers at IMS and RFIC 2010. This new research is from the labs of electrical engineering professors Gabriel Rebeiz, Lawrence Larson, Peter Asbeck and James Buckwalter. The largest number of papers is from the Rebeiz lab. The 23 papers are “… a factor of two more than any other university, and show the dominance of UCSD in this field,” explained electrical engineering professor Gabriel Rebeiz. Seven of the 28 papers in the IMS student paper award category are from UCSD. “This shows the quality of the UCSD papers,” Rebeiz said. In addition to papers, the UCSD electrical engineers will present in six workshops and two panel sessions. At IMS, Prof. Rebeiz will also receive the 2010 IEEE MTT Distinguished Educator Award.

Removing fog from video

Sunny San Diego has a foggy marine-layer side that never gets mentioned on national tv. The only way to get rid of the marine layer on some days is to drive east until it eventually disappears. When you have fog on your video, driving towards Julian is not an option...but that is where research from the video processing lab in the Department of Electrical and Computer Engineering at the UC San Diego Jacobs School of Engineering comes in.

Kris Gibson gave me a quick description of his de-hazing for video at the poster session at the Center for Wireless Communications (CWC) recent Research Review (PDF of agenda).

Single Sensor in Your Camera? Your next camera might benefit from this kind of research...

Future single-sensor cameras will surely be better at sampling all the light bands (red, green, blue) even through there is just one sensor. Ankit Jain is an electrical engineering graduate student at UC San Diego who is working on this issue.

Watch him give you a snapshot of the issue, in less than two minutes!




Ankit talked to me at last week's poster session for the Center for Wireless Communications (CWC) research review. I also talked to Cynthia Taylor "Will Starbucks Serve Servers? aka Thin-Client Computing with your Skinny Latte?"

and
Video Stabilization with Haleh Azartash

Will Starbucks Serve Servers?

Would you like thin-client computing with your skinny latte?

Tech-savy baristas may be asking you these kinds of questions, if the thin-client research that computer science PhD student Cynthia Taylor is working on takes off. At the poster session at the Center for Wireless Communications (CWC) research review on Friday, Taylor gave me a quick rundown on her research.

Take home message: she wants to turn your iPhone (and related PDAs and comm devices) into an input/output device that hooks into local servers as well as servers across the Web. This would let you do all kinds of things that are too demanding for the local computational resources of a PDA.

Window into Center for Wireless Communications (CWC) Poster Session

This is the first of four informal interviews with graduate students who presented at the UC San Diego Center for Wireless Communications (CWC) poster session today. The poster session was part of the CWC Research Review (PDF of agenda here), which happens twice per year. (Info of past reviews is here.)

This first interview is with Haleh Azartash, who is a graduate student in electrical engineering professor Dr. Truong Nguyen's Video Processing Group.

Her poster describes her work on software and algorithmic methods for minimizing and eliminating camera motion and shake in video footage: Real Time Affine Global Estimation using Phase Correlation
