Due to its flexibility, multicarrier modulation, in particular orthogonal frequency-division multiplexing (OFDM), has become very popular for transmission over frequency-selective channels. OFDM can be implemented efficiently using the discrete Fourier transform (DFT). However, due to the superposition of a (typically) large number of individual components in the transformation, the transmit signal in OFDM exhibits a large peak-to-average power ratio (PAR). This complicates the implementation of power amplifiers significantly.

In this thesis, a PAR reduction scheme using combined transmitter-side Tone Reservation (TR) and receiver-side reconstruction of clipping effects via compressed sensing (CS) algorithms is assessed. This technique requires the explicit reservation of some carriers, both for the transmitter-side TR and the receiver-side CS. The reserved carriers are not used for data transmission, which results in a lower data rate of the transmission system. To overcome this drawback, a PAR redutction technique to reduce the number of reserved tones required for the receiver-side CS while maintaining the quality of data transmission is proposed.
