Abstract(in Japanese) (See Japanese page)
Abstract(in English) Under a time-invariant condition with thermal noise, the physical limit of digital transmission ability is governed by Shannon’s channel capacity. However, in this formula, it does not contain factors on radiowave propagation environments. In other words, for the ultimate information transmission, a sufficiently long time for the coding and signal processing is expected. Since wave propagation prevents its premise, there is another physical limit for digital transmission in a different perspective with Shannon's channel capacity. Concerning this topic, our previous reports presented a new channel capacity formula by incorporating propagation parameters of delay spread and Doppler spread in Rayleigh fading environments. Based on the results, in this report, we further consider the relation between radiowave propagation and transmission ability in wide fractional-bandwidth communication systems typified by “adaptive baseband radio”.
