Performance Evaluation of MIMO System in Different PDSCH Modulation Type for Wireless Communication Using 20MHz Channel Bandwidth

In the innovation of wireless communications has probably gotten the best commitment to humanity. Wireless communications make it simple to send data from a disseverment without links or wires. The modern wireless communication (4G/5G) framework required lower power consumption, high speed data transfer rate, and bandwidth efficiency. The MIMO framework is recognized as a rival to satisfy such challenges. At the transmitter and receiver terminal, a MIMO framework uses multiple antennas to improve wireless communication system performance. This paper present a comparative analysis of bit error rate in different PDSCH modulation type (16-QAM, 64- QAM, and QPSK) in different fading channel models (EPA 0HZ, EPA 5Hz, EVA 5Hz, EVA 70Hz, Flat Static MIMO) for MIMO wireless communication. This work evaluates the performance of the $2\times 2$ and $4\times 4$ MIMO systems in different PDSCH modulation types for wireless communication using 20MHz channel bandwidth to find out which type of modulation scheme works better.
