To make the best use of all phase method in signal compression, spectrum and mul ti resolution analysis fields 〖WTBZ〗etc〖WTBZ〗, all phase signal processing algorithm in three orthogonal transforms is designed which improves weak Gibbs effectively, and the mathematical expressions and inverse transformation formula s of all phase kernel in DFT, DCT and DCT orthogonal bases are derived. Then imp lementation structure of windowed all phase processing is presented for improvi ng the performance of the algorithm. In addition, window function is analyzed fo r the linearity. Finally, two experiments, designing transmission property based on DCT and discrete wavelet transform (DWT) and sub band dividing, testify the correctness and feasibility of the presented algorithm.
