摘要：

This paper presents a CORDIC (Coordinate Rotation Digital Computer)-based split-radix fast Fourier transform (FFT) core for OFDM systems, for example, Ultra Wide Band (UWB), Asymmetric Digital Subscriber Line (ADSL), Digital Audio Broadcasting (DAB), Digital Video Broadcasting - Terrestrial (DVB-T), Very High Bitrate DSL (VHDSL). and Worldwide Interoperability for Microwave Access (WiMAX). The high-speed 128/256/512/1024/2048/4096/8192-point FFT processor has been implemented by 0.18 mu m (1p6m) at 1.8 V, in which all the control signals are generated internally. This programmable FFT processor outperforms the conventional ones in terms of both power consumption and core area. (C) 2009 Elsevier Inc. All rights reserved.
