Wideband spectrum estimation is very important for wideband wireless communication systems, especially for military communication system. The concept and the design method of the adaptive wideband spectrum estimation are put forward in this paper. Firstly, the wideband spectrum is estimated by using the wavelet packet decomposition. Then the characteristic noise of the independent signals exist in the wideband spectrum is produced by using the wavelet packet synthesis. Lastly the filters or trap filters, which are used to extract or trap signals, are designed based on LMS adaptive algorithm. The adaptive wideband spectrum estimation will be widely used in the wideband systems because of its real-time estimation ability and its good adaptability.
