| Abstract: |
We propose a new structure for polyphase synthesis in MPEG-1 audio standard. The algorithm is based on factorizing the DCT matrix in a way similar to FFT factorization. The proposed algorithm reduces the memory requirements significantly even with direct implementation. With optimized implementation, the computational requirement can be reduced considerably as well. |
