A combined space鈥搕ime block coding (STBC) and eigen-space tracking
(EST) scheme in multiple-input-multiple-output systems is
proposed. It is proved that the STBC-EST is capable of shifting
hardware complexity from the receiver to the transmitter without
any bit error rate (BER) performance loss. A computation efficient
EST algorithm is also proposed, which makes the STBC-EST affordable.
Simulation results show that the STBC-EST with a modest
feedback Requirement results in a negligible BER performance loss
compared with a dual system configuration.
online sales system of texttile mill was a project within which there was great opportunity for Learning about Internet and E-commerce. As current era is the era of Communication, and Internet is becoming the vital source of communication and Information. Online sale system of fabrics is the Requirement of evey texttile mill Associated (put) Lahore. Considering these reasons this project was developed.

This document explains the pulse compression technique. Why it is required and how can it be used effectively. The pulse compression technique helps to increase the maximum range without sacrificing the range resolution and still the power Requirement remains low.
The concept of smart cities emerged few years ago as a new vision for urban
development that aims to integrate multiple information and communication
technology (ICT) solutions in a secure fashion to manage a city’s assets. Modern ICT
infrastructure and e-services should fuel sustainable growth and quality of life,
enabled by a wise and participative management of natural resources to be ensured
by citizens and government. The need to build smart cities became a Requirement that
relies on urban development that should take charge of the new infrastructures for
smart cities (broadband infrastructures, wireless sensor networks, Internet-based
networked applications, open data and open platforms) and provide various smart
services and enablers in various domains including healthcare, energy, education,
environmental management, transportation, mobility and public safety.
Recent advances in wireless communication technologies have had a transforma-
tive impact on society and have directly contributed to several economic and social
aspects of daily life. Increasingly, the untethered exchange of information between
devices is becoming a prime Requirement for further progress, which is placing an
ever greater demand on wireless bandwidth. The ultra wideband (UWB) system
marks a major milestone in this progress. Since 2002, when the FCC allowed the
unlicensed use of low-power, UWB radio signals in the 3.1–10.6GHz frequency
band, there has been significant synergistic advance in this technology at the cir-
cuits, architectural and communication systems levels. This technology allows for
devices to communicate wirelessly, while coexisting with other users by ensuring
that its power density is sufficiently low so that it is perceived as noise to other
users.
The continuing explosive growth in mobile communication is demanding more spectrally
efficient radio access technologies than the prevalent second generation (2G) systems such as
GSM to handle just the voice traffic. We are already witnessing high levels of mobile
penetration exceeding 70% in some countries. It is anticipated that by 2010 more than half of
all communications will be carried out by mobile cellular networks. On the other hand, the
information revolution and changing life habits are bringing the Requirement of commu-
nicating on a multimedia level to the mobile environment. But the data handling capabilities
and flexibility of the 2G cellular systems are limited.
I can remember buying my first electronic calculator. I was teaching a graduate level statistics course and I
had to have a calculator with a square root function. Back in the late 1960s, that was a pretty high-end
Requirement for a calculator. I managed to purchase one at the “educational discount price” of $149.95!
Now, I look down at my desk at an ATmega2560 that is half the size for less than a quarter of the cost and
think of all the possibilities built into that piece of hardware. I am amazed by what has happened to
everything from toasters to car engines. Who-da-thunk-it 40 years ago?
