Area-Efficient 128- to 2048/1536-Point Pipeline FFT Processor for LTE and Mobile WiMAX Systems
IEEE Transactions on Very Large Scale Integration (VLSI) Systems（2015）
摘要
Fast Fourier transform (FFT) is widely used in digital signal processing and telecommunications, particularly in orthogonal frequency division multiplexing systems, to overcome the problems associated with orthogonal subcarriers. This paper presents a novel 128/256/512/1024/1536/2048-point single-path delay feedback (SDF) pipeline FFT processor for long-term evolution and mobile worldwide interope...
