Bit Error Rate Analysis of Mechanical Antenna Based on Frequency Modulation

At present, in the field of communication, there is little research on the bit error rate of mechanical antenna transmission based on frequency modulation. However, the study of BER under specific conditions is of great significance to enhance the performance of communication systems and improve the quality of data transmission. In the process of frequency modulation of mechanical antenna, the continuity of motor speed regulation will affect the continuity of signal frequency and amplitude generated by the system, which will eventually lead to high bit error rate of the system. In this paper, a mechanical antenna communication system is established to generate symbol signals of different periods. By observing the eye diagram of the baseband signal after demodulation and the relationship between SNR and BER of the mechanical antenna and the electrical antenna, the reasons for the high bit error rate of the communication system are analyzed, and the corresponding solutions are proposed.
