Abstract:Noise frequency modulation(FM)jamming。which belongs to blanket jamming。is already become the main form ofnoise jamming at present。because the wideband was gained by it.Tne spectnlnl ofnoise FM jamming is analyzed by time domain autocorrelation method in this paper.It’S jamm g peculiarity and幾out— putting signal’S jamming peculiarity ale explained.At last,these time series models ofnoise FM jalllIIling sig— nal and幾outputting signal ale built.

OpenSS7 This the fourth public release of the OpenSS7 Master Package. See README in the release for a sub-package listing. Most of the sub-packages in the release are production grade for Linux Fast-STREAMS. All existing validation test suites run clean on supported distributions and architectures. It is unlikely that the OpenSS7 Master Package will be released as frequently as before. Sub-packages will be released more often. To rebuild the master package with a new sub-package release, simply replace the directory to which the sub-package belongs with the unpacked sub-package release and then rebuild the master package. This release provides support for recent distributions and tool chains.

This book is the most accurate and up-to-date source of information the STL currently available. ... It has an approach and appeal of its own: it explains techniques for building data structures and algorithms on top of the STL, and in this way appreciates the STL for what it is - a framework. Angelika Langer, Independent Consultant and C++ Report Columnist "A superbly authored treatment of the STL......an excellent book which belongs in any serious C++ developer s library." Jim Armstrong, President 2112 F/X, Texas. \n The C++ Standard Template Library (STL) represents a breakthrough in C++ programming techniques. With it, software developers can achieve vast improvements in the reliability of their software, and increase their own productivity.

The 4.0 kbit/s speech codec described in this paper is based on a Frequency Domain Interpolative (FDI) coding technique, which belongs to the class of prototype waveform Interpolation (PWI) coding techniques. The codec also has an integrated voice activity detector (VAD) and a noise reduction capability. The input signal is subjected to LPC analysis and the prediction residual is separated into a slowly evolving waveform (SEW) and a rapidly evolving waveform (REW) components. The SEW magnitude component is quantized using a hierarchical predictive vector quantization approach. The REW magnitude is quantized using a gain and a sub-band based shape. SEW and REW phases are derived at the decoder using a phase model, based on a transmitted measure of voice periodicity. The spectral (LSP) parameters are quantized using a combination of scalar and vector quantizers. The 4.0 kbits/s coder has an algorithmic delay of 60 ms and an estimated floating point complexity of 21.5 MIPS. The performance of this coder has been evaluated using in-house MOS tests under various conditions such as background noise. channel errors, self-tandem. and DTX mode of operation, and has been shown to be statistically equivalent to ITU-T (3.729 8 kbps codec across all conditions tested.
