Peak-to-average power ratio reduction in OFDM based on transformation of partial transmit sequences
A novel scheme (transformation of partial transmit sequences, T-PTS) is proposed for the partial transmit sequence (PTS) method to reduce peak-to-average power ratio of OFDM signals. In T-PTS certain transformations are applied on partial transmit sequences to generate more candidates for increasing performance. Simulations show that T-PTS outperforms conventional PTS for the same number of subblocks; and both schemes have similar performance for the same candidate number, but T-PTS is less complex.
