Abstract

Following a 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 often used in digital transmission systems. The implementation issues of the CORDIC-algorithm in programmable logic devices is illustrated by the example of a versatile transmission system for digital terrestrial television.
