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.
