Evaluation of the weighted-overlap add model with massive MIMO in a 5G system

The flaw in 5G orthogonal frequency division multiplexing (OFDM) becomes apparent high-speed situations. Because the doppler effect causes shifts, orthogonality of OFDM subcarriers is broken, lowering both their bit error rate (BER) and throughput output. As part this research, we use a novel design that combines massive multiple input output (MIMO) weighted overlap add (WOLA) to improve performance systems. To determine which superior, BER are calculated for proposed OFDM. results improved system show improvement ver conventional significant improvements with MIMO, including best BER. When compared systems, has around 22% higher terms BER, but it still 25% less than
