Description: 分析了在超宽带通信系统中的扩频干扰，并用两种通用的调制技术实现了对提出的抗干扰方法的仿真-he ultra wideband (UWB) interference to direct
sequence spread spectrum (DSSS) receiver is analyzed. Two
popular UWB modulation schemes, the time hopping pulse
position modulation (TH-PPM) and time hopping pulse
amplitude modulation (TH-PAM), are considered. The pulse
repetition rate (T’RR) of UWB signal and the freqnency hand of
the DSSS play the primary roles in the BER performance of the
DSSS receiver in the presence of UWB interference. The UWB
signal parameters raising the interference to DSSS receiver are
discussed. The characteristics of an aggregation of multiple
UWB signals are somehow different from that of a single UWB
device, especially for the TB-PPM scheme, where discrete
spectral lines maybe exist in the band of DSSS receiver. The
system parameters of TH-PPM such as the modulaiion index
and maximum shift incurred hy the time hopping code
determine the amplitude of the discret

Description: Imaging is native Object Pascal image loading, saving and manipulation library. It is available for several platforms and does not require any third party dynamic libraries or other compiled binaries.
Main development language is Object Pascal (Delphi and Free Pascal compilers are supported) and there are interfaces to the library (compiled into dll/so) for other languages like C/C++ and Delphi.NET. Currently supported operating systems are Windows, Linux, FreeBSD (and some other Unixes), and Mac OS X (on Intel). Supported CPU architectures are x86 and AMD64.
Currently supported image file formats are: (loading and saving) BMP, JPEG, PNG/APNG, GIF, TGA, DDS, MNG, JNG, JPEG2000, PSD, TIFF, PGM, PPM, PAM, PFM, XPM, (loading only) PCX, and PBM. Many internal image data formats are supported: 8/16/24/32/48/64 bit RGB and ARGB formats, indexed formats, grayscale formats, half/single precision floating point formats, and compressed formats DXT1/3/5, 3Dc, and BTC.
