Abstract: The pseudonoise-code acquisition for direct-sequence spread-spectrum(DS/SS) systems in weakly dependent non-Gaussian impulsive channels is considered.Modeling the acquisition problem as a hypothesis testing problem,a detector is derived for weakly dependent non-Gaussian impulsive noises based on the locally optimum detection technique.Numerical results show that the proposed detector can offer an substantial performance improvement over the conventional schemes in dependent non-Gaussian impulsive noise channels.
