| description | Digital terrestrial video broadcasting systems based on orthogonal frequency division multiplexing (OFDM), such as second generation of terrestrial digital video broadcasting standard (DVB-T2), often include carriers reserved for peak-to-average power ratio (PAPR) reduction. This paper presents a low-complexity PAPR reduction method that inserts coded data onto a subset of reserved carriers. Using differential binary phase shift keying (DBPSK) with repetition coding, the proposed method generates a time-domain peak-cancellation signal that carries additional information. The carrier selection and the signal amplitude of the coded DBPSK data is optimized, also to avoid the regrowth of other peaks. Simulation results show that the proposed algorithm outperforms the tone reservation (TR) algorithm of the DVB-T2 standard in terms of both PAPR reduction performance and computational complexity. The proposed algorithm is also significantly less complex than the clipping-and-filtering (CF) algorithm and than the active constellation extension (ACE) algorithm of the DVB-T2 standard, despite lower reduction of PAPR. Since the proposed method modifies only the reserved carriers of DVB-T2, the compatibility with existing DVB-T2 receivers is fully guaranteed. |
