The MIMO-OFDM is the prevailing candidate for 4G and 5G broadband wireless communications. This technology is widely adopted in a variety of communication standards like LTE and LTE advanced. It combines multiple inputs and multiple outputs which improves the capacity by transmitting different signals over multiple antennas and orthogonal frequency division multiplexing which divides a radio channel into a large number of closely spaced sub channels to provide more reliable communications at high speed. The most important blocks in LTE 4G are OFDM symbols generation and OFDM symbols reception based on IFFT and FFT. In this paper, we attempt to optimize these blocks to ensure the multicore aspect of MIMO-OFDM LTE.
