A new efficient implementation of TDAC synthesis filterbank based on Radix-2 FFT
Anup K.C, Ajay Kumar Bangla · European Signal Processing Conference · 2006
An improved implementation of the TDAC synthesis filterbank is proposed which is well suited for fixed point implementation on embedded platforms. The new implementation is based on computation of IMDCT by Radix-2 FFT. A new fast and regular structure has been derived by modifying the pre-processing, FFT and post-processing stages of the implementation. An efficient implementation of windowing for embedded platforms is also suggested.
