【 摘 要 】

Today's interference methods to the receiver include human jamming and non-human interference, and the human one can be divided into two types - suppressing jamming and spoofing jamming. In the spoofing jamming, the jamming source transmits or generates interference signal, trapping the receiver into a wrong location and time estimation of signals from receiving the real signal. Due to its strong similarity to the real one, the interference signal is difficult to be detected and suppressed by the receiver. Thanks to the similarity between spoofing jamming signal and multipath signal, the thesis aims to improve and optimize the WRELAX algorithm - by detecting and identifying signals after WRELAX algorithm according to the multipath fading, we can, finally, separate the spoofing jamming signal and real signal.
