On Particle Swarm Optimization for MIMO Channel Estimation

Algorithm 1

Standard PSO algorithm.

Initialize swarm

Locate leader

𝑖=1

while  𝑖<𝑖_max or convergence do

 for each particle do

  Update position using (1)/(2),  (4)

  Evaluation using  (5)

  Update pBest

 end  for

 Update leader

 𝑖++

end  while
