Research on Adaptive Modulation and Demodulation Technology for Communication Systems Integrating ADC and FPGA
To improve the effectiveness of signal modulation and demodulation in communication systems,an adaptive modulation and demodulation scheme is designed by combining analog-to-digital converters(ADC)and field programmable gate arrays(FPGA).ADC is responsible for converting ana-log signals into digital signals,while FPGA takes on the task of signal processing.It can dynamically select the most suitable modulation and demodulation methods based on actual channel conditions and transmission requirements.Experimental data shows that the signal transmitted into the FPGA has a minimum bit error rate of 19.183%after pulse width modulation(PWM)and ADC demodulation.Compared to traditional FPGA demodulation methods,the signal demodulated by ADC has a lower bit error rate,which can improve the application effect of communication networking technology.
