Comparitive Study of Hybrid Precoding Algorithms for millimeter wave Communication Systems

The evaluation of millimeter wave and massive MIMO is consider as a reliable technique for future 5G cellular wireless communication systems. As the bandwidth and frequency spectrum increases, the magnitude also shows a rise. The antennas used here are small in size but large in number is computed as precoder at transmitter and combiner at receiver with less number of training data streams. In is paper both algorithms, PE-AltMin and Kalman hybrid precoding are compared and in those algorithm analog and digital precoding are selected from the codebook which introduces the simulation result a high spectral efficiency was received when varying SNR low to High and number of users also increased small to large.
