Research Prototypes

Compact switched parasitic array (SPA)

AIT B-WiSE group was the pioneer in designing, optimizing and implementing a compact parasitic antennas with a single RF chain for emulating MIMO terminal by parasitically controlling the active element of the SPA. (see figure)
The antenna design and development was performed in collaboration with Julien Perruisseau-Carrier (CTTC).

Mimo testbed

B-WiSE Group has a 2x3 MIMO testbed which can be found here.

With this testbed and the SPA anlague MIMO transmission with 1 RF front end has been achieved. Following are the specification used for the MIMO transmission experiment used for 3-element ESPAR antenna array.

BPSK Modulation

Baseband Frequency - 500 kHz

Baseband signal - Raised cosine

Training sequence - 8 symbols

Burst size - 410x2 symbols

Switching signal level - 8 V

V-BLAST with Zero Forcing Equalizer at the receiver

The Bit Error Rate (BER) is calculated by comparing the bit streams. BER performances are evaluated with different SNR levels. The following Figure shows a comparison of BER performances with SNR for three scenarios.

Students' Views

"It was amazing how appealing the idea is of having a CMU education with a Greek touch! Plus, I was able to stay close to home and visit my friends and family often."

AIT's 1st Gaming Forum a Success!
2012-05-11

AIT's 1st Gaming Forum was a two day celebration of Gaming that brought together the Greek gaming industry with academics and gaming enthusiasts of all ages. The Gaming Forum was co-organized with the British Council and Cowboy Tv and realized thanks to the support of Grand Sponsor hellas online, Gold Sponsor intralot, Sponsor the EU project KnowInG and Grand Communication Sponsor MTV.

17 High School students participated in the ATHENA Exchange program co organized by AIT & INTRACOM Albania
2012-05-07

17 students and 3 professors from Arsakeio, Harry Fultz, Ismail Qemali, Sami Frasheri and Petro Nini Luarasi schools, spent 4 days of cultural and educational experiences.

Open Invitation to AIT Research Seminar, April 10, 2012
2012-04-03

AIT is pleased to invite you to a Research Seminar on "Technology-enabled social learning.". The Seminar will be conducted by Mr. Hristijan Petreski, Project Manager, Intracom.

AIT Alumni Club has 44 new members!
2012-03-16

"It is not the solution all of us to go abroad" said Mr. Robby Bourlas, Managing Director of the Public, Multirama and getitnow.gr addressing to 44 students representing Greece, Cyprus, Jordan, Romania, Malawi, and Armenia, graduated with a MSc in Management of Business, Innovation & Technology (MBIT) from AIT. "You can still find business opportunities in Greece, as long as you believe it. In a difficult period like the one we live in, it is just harder to find these opportunities."
