                             9TH DAY DIARY
                                  Of
         School on Radio use for digital and multimedia communication

21 February 2002

With a nice morning, and beautiful but cloudy weather, we started our
9th day in the use of Radio in digital and multimedia communication
school. Mr. M. Fitton (Toshiba, Bristol) presented the first lecture on
Principles of Digital Modulation. His whole lecture was very interesting
and informative. He expressed it in an excellent manner with fluent
English. At 10:30 a.m., he gave a 15 minutes break to relax the
participants. At 10:45 he again started his lecture and also explained
his second topic "Mobile and Personal Communications". His graphical and
colorful slides were very informative and I really came to know about
the exact difference of CDMA, FDMA and TDMA. I also found Mr. M. Fitton
a very punctual man because he finished his lecture right at 12 O'clock.
After that, we took our lunch break, and also took tea in a bar which
was fined to our friend Anwar Ali Sanjrani due to his absence in lunch
and for wasting our time for his wait. The afternoon session starts with
Participants Case Study Presentation. Mr. Abakir T.Tchekirov (Bishkek,
Kyrgystan) presented the first case study on "Information Technologies
in Kyrgyz Republic". He described the Network Infrastructure existing
presently in his country with respect to the geographical locations and
spread, and types of technology used. Carlos Avendano (Medillin,
Colombia) made the Second presentation. Highlights of his presentation
were the Satellite station, Radio Link and private WAN networks. Coming
up next was Ngatched Telex from Durban, SouthAfrica. He delivered a
paper describing the Stopping Criteria for Turbo Decoding and Turbo
Codes for Burst Channels. He was quick to point out the role of Turbo
Codes because he had only 15 minutes to explain which was not enough for
him but the idea was very nice and all the participants including Mr. M.
Fitton (Toshiba) appreciated him. O.S.Adewale (Akure, Nigeria) made the
fourth presentation on "Causes and Cure of Latency in the Internet
Telephony". He said that Internet telephony is a transport of Telephone
calls over the Internet, no matter whether traditional telephony
devices, multimedia personal computers or dedicated terminals part in
the calls and no matter whether the calls are entirely or only partially
transmitted over the Internet. Coming up next were Kundukulam and
Karuvandy (India). They delivered their presentation on a Compact Dual
Frequency Microstrip Antenna. The presentation was on a very nice, new
and efficient idea on the design and development aspects of a microstrip
antenna. This antenna can transmit or receive two frequency bands, which
are of orthogonal polarization. Their coordination was also very nice
because the slides were moving according to their presentation.

After a short break, Gbenga-Ilori, A.O. (Department of Electrical and
Electronic Engineering Akure, Nigeria) delivered her presentation titled
"Technical Aspects in Channel Planning for Digital Terrestrial
Television Broadcasting". She described the Evolution of Digital
Broadcasting, Channel Planning Methodology, Types of Interference,
protection Ratio Parameters and some statistics about channels in her
country. After this presentation, Prof. Radicella announced a break for
8:00-10:00 a.m. for the next day (Friday 22nd Feb. 2002) on the greatest
Holly Event of Muslims (Eid-ul-Azha), for praying Namaz-Eid. All the
participants of the school appreciated the decision of Prof. Radicella
and congratulated the Muslim community for this great day. The next
presentation was by M.O.Sokunbi (lle-lfe, Nigeria). He presented his
case study on "The Socio-economic Impact of Information Technology on
the Obafemi Awolowo University Campus". He strongly recommended the use
of information technology for the fast development in his country. After
that Jean A.Agoua (UAB Cotonou, Benin), presented his survey on
Distributed Computing Networks-Networks of Workstation. His presentation
includes, aim and composition of Distributed Computing Networks,
challenges and opportunities for network of workstations and a case
study about the database on climate changing in Benin. Last but not the
least was an interesting presentation by Sunil Vasant Rao (India), on
the Improvement of Railway System. The thought provoking, interesting
sessions finally ended at 6.00 p.m. All the sessions and presentations
were held in a very friendly and interactive manner. They were very
informative, educative and stimulating to set up inquisitive and
learning atmosphere in the school.
