摘要：
Following a short description of the Fast-Fourier-Transformation (FFT) this paper discusses the advantages of the CORDIC-algorithm [1], [2] (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.
