It has long been suspected that the non-cutoff Boltzmann equation enjoys similar regularity properties as to whose of the fractional heat equation. We prove that any solution with mild regularity will become smooth in Gevrey class at positive time, with a sharp Gevrey index, depending on the angular singularity. Our proof relies on the elementary L^(2) weighted estimates.展开更多

It can provide a maximum bit rate of 13.9 Mb/s thereby dramatically extending the transmission rate and spectrum efficiency of R99 version. Currently, it is the first choice of mobile operators for high bit rate mobile multimedia services. All the mobile technologies and their characteristics, which are employed by HSDPA system in WCDMA, are analyzed in the following. The possible applications of HSDPA are also discussed in this article.展开更多
