| Abstract: | The time-frequency characteristics the HF channel such as Doppler and multipath spread cause an irreducible error probability in digital radio system. Using the auto-receiving measuring system of the short wave time frequency service signal and envelope method, the Doppler and Maltipath spread is measured. In term of the measured resules, the time-frequency characteristics of the two parameters and their influence on the performances of the digital communication systems are emphatically discussed here. |
