Power Allocation for Reducing PAPR of Artificial-Noise-Aided Secure Communication System
Algorithm 4
The triple-iterative algorithm for the optimization problem (4).
Input: transmit antenna number , legal channel , PA parameter for different SNR values (according to reference [47]), modulation symbol with a finite alphabet, AN vector ;
Output: PA matrix , optimized PAPR value ;
(1)
Initialize the PAPR value , and the maximum tolerance and the iteration index ;
(2)
Repeat {Main Loop}
(3)
Initialize the PA matrix , and the iteration index ;
(4)
Repeat {Main Loop}
(5)
Initialize the iteration variable ,, iteration step length , and the iteration index ;
