Huffman codes
1.In telecommunication, how do we represent a set of messages, each with an access frequency, by a sequence of 0 s and 1 s?
2.To minimize the transmission and decoding costs, we may use short strings to represent more frequently used messages.
3.This problem can be solved by using an e ...
A simulated lexical analyser for HLL like C,PASCAL etc. I have given a sample text file from which the source code reads the dummy
program n analyses it. The program can be extended by adding more.
Rotation tool, totates a single image contained in HANDLE.HANDLE can be a handle to figure, axes, or image object.
This GUI is a pure imitation of ROTATEGUI from Birju Patel and uses some code from that function. However, it has extended functionalities and was re-writen using R13 syntax. Which mean ...
Why do People Program?
Each person can have his own reason for programming but I can tell you that programming is one of the best ways to gain a deep understanding of computers and computer technology. Learning to program makes you understand why computers and computer programs work the way they ...
X-MAC, a low power MAC
protocol for wireless sensor networks (WSNs). Standard
MAC protocols developed for duty-cycled WSNs such as
BMAC, which is the default MAC protocol for TinyOS, employ
an extended preamble and preamble sampling.
DESCRIPTION
The Texas Instruments MSP430 family of ultra-low-power microcontrollers consists of several devices featuring
different sets of peripherals targeted for various applications. The architecture, combined with five low-power
modes, is optimized to achieve extended battery life in portable m ...
When joining Siemens in 2001, I also extended my research interest towards radio net-
work planning methodologies. This area of research brought together my personal interest
in mobile communications and in the design of efficient algorithms and data structures.
Between 2001 and 2003, I participated ...
Wireless Fidelity (Wi-Fi) networks have become mainstream over the last few years. What
started out as cable replacement for static desktops in indoor networks has been extended
to fully mobile broadband applications involving moving vehicles, high-speed trains, and
even airplanes.
The insinuation of telecommunications into the daily fabric of our lives has been
arguably the most important and surprising development of the last 25 years. Before
this revolution, telephone service and its place in our lives had been largely stable
for more than a generation. The growth was, so t ...
It was only a few years ago that “ubiquitous connectivity” was recognized as the future of
wireless communication systems. In the era of ubiquitous connectivity, it was expected that
the broadband mobile Internet experience would be pervasive, and seamless connectivity on
a global scale would be n ...
