Construction of Frequency-Hopping System Using Carrier-Signal Generator

To clearly understand wireless communication technology for educational purposes, an inexpensive wireless modulation and demodulation system is required. A simple carrier-signal generator can generate a carrier signal, and a spectrum analyzer can search for a peak frequency and be controlled by a PC. Therefore, a frequency-hopping wireless transmitter and receiver system can be constructed using a carrier-signal generator and spectrum analyzer. We constructed a frequency-hopping transmission system using a carrier-signal generator and spectrum analyzer. To validate this system, we evaluated the peak frequency detection probability and compared it with theoretical values. The results indicate that when the hopping time interval was 2000 ms, the peak frequency detection probability almost coincided with the theoretical values.
