摘要

本文在简要介绍快速傅里叶变换(FFT)之后，讨论了cordic算法(坐标旋转数字计算机)相对于蝴蝶运算中的复杂乘法和许多数字传输系统中使用的数控振荡器(NCOs)的优点。以数字地面电视通用调制器为例，说明了cordic算法在可编程逻辑器件中的实现。

Benefits of the CORDIC-algorithm in a versatile COFDM modulator/demodulator design

Following a short description of the Fast-Fourier-Transformation (FFT) this paper discusses the advantages of the CORDIC-algorithm (Coordinate Rotation Digital Computer) compared to complex multiplication in butterfly-operations and NCOs (Numerical Controlled Oscillator) which are used in many digital transmission systems. The implementation of the CORDIC-algorithm in programmable logic devices is shown by the example of a versatile modulator for digital terrestrial television.
