This example application is a collection of Flash Lite do s and don ts from the
usability point of view. The application contains real examples and animations
of static examples that help you to see problematic issues in real life on a
Nokia device. The application is optimized for devices with the resolution 170 x 208
pixels used in portrait mode.
This example application is closely related to the document Flash Lite: Visual Guide,
and it is highly recommended to read the document before going through this example.
This paper investigates the design of joint frequency
offset and carrier phase estimation of a multi-frequency time division
multiple access (MF-TDMA) demodulator that is applied to
a digital video broadcasting—return channel system via satellite
(DVB-RCS). The proposed joint estimation algorithm is based on
the interpolation technique for two correlation values in the frequency
and phase domains. This simple interpolation technique
can significantly improve frequency and phase resolution capabilities
of the proposed technique without increasing the number of
the correlation values. In addition, the overall block diagram of a
digital communications receiver for DVB-RCS is presented, which
was designed using the proposed estimation algorithms.
Index Terms—Carrier phase estimation, DVB-RCS, frequency
offset estimation, interpolation, joint estimation, MF-TDMA.

Make your graphics look better with an easy-to-use
JPEG 2000 decoding component. J2K-Codec can help
game developers, screensaver creators and many
others to improve their products--to achieve better
image quality and reduce installation package size.
The new image compression standard based on wavelet
technology has many interesting features not
available in the old JPEG, such as alpha-channel
and varied resolution levels.
Uniform random number generators
by Agner Fog, 2001 - 2007
randomc.zip contains a C++ class library of uniform random number generators of good quality.
The random number generators found in standard libraries are often of a poor quality, insufficient for large Monte Carlo calculations. This C++ implementation provides random number generators of a much better quality: Better randomness, higher resolution, and longer cycle lengths.
The same random number generators are available as libraries coded in assembly language for higher speed. These libraries can be linked into projects coded in other programming languages under Windows, Linux, BSD, etc. The library files are available in the archive asmlib.zip.
Non-uniform random number generators are provided in stocc.zip.
sfrmat is a Matlab function that provides a spatial frequency response* (SFR) from a digital image file containing a slanted-edge feature. The specific edge-gradient algorithm follows the intent of the standard ISO 12233, developed by Technical Committee ISI/TC 42, for resolution measurements for electronic still pictorial cameras.
After an introduction to the history of mobile communications, this guide considers the basics of mobile radio, the design of cellular and private radio systems, and issues of interworking with the fixed network. It then looks at the role of the mobile radio operator, the design and operation of mobile radio networks, the needs of large user groups, and relevant regulatory and government decisions. A final section focuses on career development through resolution of conflicts, understanding managerial issues, and professional vehicles.
LCD Driver datasheet
The SPF54126A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of
supporting up to 176xRGBx220 in resolution which can be achieved by the designated RAM for graphic data. The 528-channel source
driver has true 6-bit resolution, which generates 64 Gamma-corrected values by an internal D/A converter. The source driver of
SPFD54126A adopts OP-AMP structure to enhance display quality and it cooperates with advanced circuitry techniques to reduce power
consumption.
