Detection performance and robustness of segmented replica correlator processors in fast fading distortion channels

In order to improve the robustness of detectors, this paper concentrates on the approach that based on modeling the channel distortion as fast fading distortion (FFD). The influence on revising medium propagating under this model is analysis. The generalized likelihood ratio test (GLRT) yields an optimal detector. This detector is the segmented replica correlator (SRC). It can subdivide the correlation processing into segments that are later incoherently combined. In this paper, we give the waveform distortion mechanisms and optimum receiver structures. The false alarm probability and detection probability are analysis. Numerical simulations and experimentations based on linear frequency modulated (LFM) signal are used to demonstrate the accuracy of our analysis. The result show the SRC detector can improve detection performance in reverberation when the channel distortion is modeled as FFD.
