摘要

In order to overcome the high PAPR of OFDM (Orthogonal Frequency Division Multiplexing) signal, a construction method of multi-phase orthogonal matrix family is proposed and its nature is analyzed in this paper, at the same time, two kinds of low-PAPR OFDM algorithm for guaranting the data security are designed by using multi-phase orthogonal matrix. Theoretical analysis and simulation results show that the matrix number of orthogonal matrix family is N!×NN. Through taking any matrix as a key and multiplying the OFDM input signals, the PAPR can be reduced without introducing error rate, and the data security is guaranteed at the same time.
