QPSK
Direct sequence spread spectrum (DSSS) communication systems has been widely
used in these years for its advantage of wide spectrum, low working Signal-to-Noise
ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD.
They are increasingly replacing conventional communication forms and obtaining
extensively applications in modern military and commercial communication systems,
for example, CDMA communication system, GPS , measuring and control system,
satellite chain, identification of friend or foe and etc. Therefore, corresponding DSSS
electronic counter technique becomes a big problem to solve in electronic warfare
domain. DSSS electronic counter technique including blind detection, blind parameter
estimation and spreading sequences estimation. For the issue of DSSS electronic
counter technique of DSSS/QPSK signal damaged by strong additive white Gaussian
noise (AWGN), the main research content in this dissertation as follow.

DRTOOL_drtoolbox
matlab 降维工具箱,最新版本。包含各类线性及非线性降维代码,lle,lpp,mvu,isomap,npe等皆在其中。(DRTOOL, by itself, creates a new DRTOOL or raises the existing
singleton*.
H = DRTOOL returns the handle to a new DRTOOL or the handle to
the existing singleton*.
DRTOOL( CALLBACK ,hObject,eventData,handles,...) calls the local
function named CALLBACK in DRTOOL.M with the given input arguments.
DRTOOL( Property , Value ,...) creates a new DRTOOL or raises the
existing singleton*. Starting from the left, property value pairs are
applied to the GUI before drtool_OpeningFunction gets called. An
unrecognized property name or invalid value makes property application
stop. All inputs are passed to drtool_OpeningFcn via varargin.
*See GUI Options on GUIDE s Tools menu. Choose "GUI allows only one
instance to run (singleton)".)
