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.
