Improved implementation of the Princen-Bradley filter bank
D. Šević, Miodrag V. Popovic · IEEE Transactions on Signal Processing · 1994
An improved implementation of the Princen-Bradley filter bank is proposed. The new implementation is based on the use of the fast Fourier transform algorithm of real-valued sequences. Compared to the previous solutions, it has less additions, simpler structure of modules, and permits parallel execution.>
