Abstract: A structure of blind adaptive frequency-shift filter is discussed in this paper. Based on this filter, a mutual interference rejection technology is introduced for combining TDD cell and Ad hoc network. By using the cyclostationarity of the desired signal and interference signals as well as the correlation of input and output, the technology can extract the desired signals from spectrally overlapping interferences by knowing just only the cycle frequencies of the signals. The technology does not require training signals and knowledge of the statistics of the desired signal. Thus the complexity of the system is reduced. Not only the realization of blind adaptive FRESH filter is discussed, but also its performance is simulated and analyzed. The simulation results prove that the technology can perfectly filter the interference.
