Analog Codes for Peak-to-Average Ratio Reduction

| Multi-tone modulation (DMT, Discrete Multitone, OFDM, Orthogonal Frequency Division Multiplex) has the disadvantage of a quite high peak-toaverage ratio. Clipping of the high amplitudes caused by the analog circuitry leads to additional noise. In this contribution we show that in principal, so-called Analog Codes (Reed-Solomon Codes over complex numbers) can be used for eliminating this noise.
