Name: Alternate FFT Structures
ID: m12012
Language: English (en)
Summary: FFT structures with different memory layout and interconnection patterns are occasionally useful for certain applications. These alternate structures include decimation-in-frequency FFTs with in-order outputs, decimation-in-time FFTs with in-order inputs, structures with both in-order inputs and outputs, and constant-geometry structures with the same connection pattern in every stage.
Subject: Science and Technology
