In this paper, pilot carriers are designed using particle swarm optimization method. It is compared with random and orthogonal placement of pilot that is used for LS channel estimation in MIMO OFDM systems. Channel estimation is done with the help of bit error rate and mean square error corresponding values of signal to noise ratio. In this paper, the position of pilots is also investigated. Mat lab software is used to design a pilot. According to the simulation results, PSO is an effective solution for designing pilot carriers.
