Simulation Study on a 5G FBMC-16QAM Anti-interference System
To address the interference issues in 5G communication systems,this paper proposes a method that combines the filter bank multicarrier(FBMC)with quadrature amplitude modulation(QAM),aiming to better mitigate adjacent subcarrier interference and improve power efficiency while reducing out-of-band attenuation.A 16QAM modulation and demodulation scheme based on the 5G FBMC system is designed and analyzed by utilizing constellation diagrams and simulation curves of the error rate for FBMC-16QAM modulation and demodulation.The results show that in this system,the error rate decreases gradually with increasing signal-to-noise ratio.Moreover,under the same signal-to-noise ratio,the error rate also increases as the modulation order increases.
