Abstract

The use of a set of fixed permutations has recently been proposed for peak-to-average power ratio (PAR) reduction of an OFDM signal. Sending the identity of the used permutation to the receiver reliably is critical in this method. This paper presents the use of data permutation with embedded side information (SI) to reduce the PAR of an OFDM signal. SI is coded using a simple forward-error-correction code and inserted into the information sequence. The PARs of the permuted sequences and the original information sequence are then computed using IDFTs. The sequence with the lowest PAR is chosen for the transmission. The PAR statistics do not degrade due to the inclusion of SI. This paper also presents theoretical expressions for the complementary cumulative density function (CCDF) of the PAR of an interleaved OFDM (IOFDM) signal and for the average number of interleavers in the adaptive interleaving approach.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
