Abstract :
In this paper, we presented our latest measurement results of both channel attenuation and noise within the frequency range of 1-40 MHz. Results show both attenuation and noise characteristic are quite stable, not changing drastically with time. The attenuation increases with the increase of frequency while the noise level drops with the increase of frequency. This means the channel can naturally provide certain balance on signal-to-noise ratio to facilitate the system design. Theoretical channel capacity is calculated using water-filling algorithm, which is also helpful in the system design
