PAPR Reduction Using Fireworks Search Optimization Algorithm in MIMO-OFDM Systems

Algorithm 1

Employ FWA based PTS to reduce the PAPR.

(1)	Set general input parameters, stopping criterion, phase factors, etc;
(2)	select N locations for fireworks randomly;
(3)	computing the fitness of each seeds (PAPR);
(4)	while stop criteria is not met do
(5)	Set off n fireworks respectively at the n locations:
(6)	for each firework do
(7)	Calculate the number of sons that each firework should generate (10);
(8)	Calculate the amplitude of each individual (sparks) Ai (11);
(9)	end for
(10)	for k = 1 to (number of generated sparks by Gaussian Mutation Operator) do
(11)	Generate a specific spark for a randomly selected firework ;
(12)	end for
(13)	selection strategy to choose the best sparks for next generation using the selection probability given in (15);
(14)	end while
