ICASSP 2015 Recap
This year, the flagship conference for Signal Processing, ICASSP-2015, was in the beautiful city of Brisbane, Australia. As in other years, many of the leading scientists, researchers, and students came together to share ideas and present their work. I was one of the lucky ones who made it to the conference and had the opportunity to learn about the latest developments in research and science. I would like to give you a small snapshot of what I have found as some of the promising fields in signal processing, reflecting my area of interest in direction-of-arrival-estimation (DOA), beamforming and localization in which I have worked for more than 10 years as a researcher and professor at Middle East Technical University, and as a practicing engineer at ATARGET.
Massive MIMO is becoming an essential element of wireless communication and one of the hottest topics in recent years. It has been pointed out that in two years, two billion wireless devices compatible with IEEE 802.11ad standard will be in use. IEEE 802.11ad supports 7 Gbits/s rate at 60 GHz. In addition, beamforming is used for robust communication by employing a large array of antennas (hence Massive MIMO). Since these devices have small form factor and computational/power resources, simple signal processing algorithms should be implemented. The challenge is discovering efficient algorithms for DOA estimation, beamforming and communication techniques that will work with limited computational resources. Obviously developing simple but effective algorithms requires ingenuity and hard work.
Millimeter-wave (mm-wave) communications is another topic which draws a lot of attention due to its promise for delivering large chunks of bandwidth. An interesting combination is mm-wave MIMO systems. Research in this area indicates that mm-wave communication cannot be performed without the help of beamforming since the SNR before the array gain is as low as -30dB; therefore, mm-wave systems will have limited power and computational resources. Hence simple beamforming and signal processing schemes should be employed for such devices.
At ICASSP 2015 there were several sessions devoted to DOA estimation, beamforming, and localization with applications in communications, radar, sonar, audio, and speech. I believe that this trend will continue for some time as the market drivers, including the development of 5G communication systems, influences researchers to develop innovative solutions. I am happy to see, therefore, that the book I edited with Benjamin Friedlander is still relevant and is a good resource for anybody who would like to learn about the fundamentals in DOA estimation, beamforming and localization.
