On multidimensional inverse scattering under the Stark effect
Tadayoshi Adachi, Yuta Tsujii
We study one of multidimensional inverse scattering problems for quantum systems in a constant electric field, by utilization of the Enss-Weder time-dependent method. The main purp…

Analysis of Finite Field Spreading for Multiple-Access Channel
Guanghui Song, Yuta Tsujii, Jun Cheng +1
Finite field spreading scheme is proposed for a synchronous multiple-access channel with Gaussian noise and equal-power users. For each user, information bits are spread \emph{…
