为提升通信系统信号调制解调的效果,研究结合模数转换器(ADC)和现场可编程门阵列(FPGA)设计自适应调制解调方案.ADC负责将模拟信号转换为数字信号,FPGA承担信号处理的任务,它可以根据实际信道条件和传输要求,动态选择最适合的调制方式和解调方式.实验数据显示,传入FPGA内部的信号通过脉冲宽度调制(PWM)和ADC解调后,其误码率最低为19.183%.相比于传统FPGA解调的方法,ADC解调后的信号具有较低的误码率,能够提升通信组网技术的应用效果.
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.
