GAO Qing-wei 1,CHENG Yu-lin 2,MING Jun 2 1( Anhui university Department of Automation, Hefei 230039,China) 2(Anhui University Department of Elactronic Engincering and Information Science,Hefei 230039,China)  
In the paper we analysis quadrate wavelet and biorthogonal wavelet attaining subband decomposition and perfect-reconstruction of signals throughing conjugate filter and biorthogonal filter banks, and report several method of arbitrary longth signal extension and its appling in multimedia image compress coding.
