    In this research, we propose a new design method for the generalized linear-phase lapped orthogonal transforms (GenLOT). The GenLOT is based on the DCT and has fast implementation algorithm. Generally, the lattice structure is used for its design and implementation. Consequently, nonlinear optimization is required for its design process. In our proposed method, filter coefficients are optimized directly and this method require only to solve linear equations iteratively. Moreover, this algorithm converges within a few iteration.
