In order to satisfy the demands of 5G wireless networks, QAM (quadrature amplitude modulation) becomes an essential technology to achieve faster data speeds and enhanced spectrum efficiency. This work presents the design and modeling of a 5G-specific QAM modulator and demodulator. The suggested architecture makes use of cutting-edge QAM methods to improve system resilience and data transfer speeds. The simulation uses MATLAB and Simulink to test how well the modulator and demodulator work in different channel conditions. It shows improvements in bit error rate (BER) and signal to noise ratio (SNR). The results show that the QAM system works well to meet the strict requirements of the fifth generation of wireless networks, making it possible for people to communicate quickly clearly.

摘要

In order to satisfy the demands of 5G wireless networks, QAM (quadrature amplitude modulation) becomes an essential technology to achieve faster data speeds and enhanced spectrum efficiency. This work presents the design and modeling of a 5G-specific QAM modulator and demodulator. The suggested architecture makes use of cutting-edge QAM methods to improve system resilience and data transfer speeds. The simulation uses MATLAB and Simulink to test how well the modulator and demodulator work in different channel conditions. It shows improvements in bit error rate (BER) and signal to noise ratio (SNR). The results show that the QAM system works well to meet the strict requirements of the fifth generation of wireless networks, making it possible for people to communicate quickly clearly.
