| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | MIMO(Multiple-Input Multiple-Output) transmission technologies are expected to increase the system capacity within the same frepuency bandwidth with multiple antennas at both transmitter and receiver in wireless communications systems.When the number of user antenna is less than the antenna number of access points in the MIMO technology, high transmission capacity cannot be expected.Then, multi-user MIMO(Multi-user MIMO) technology is researched to achieve high transmission capacity in recent years.The null control method of the Zero- Forcing standard and the Linear Processing known as conventional methods have not been examined in study of the space correlation and the eigenvalue under real propagation environment.This report presents compare for both methods under multiuser MIMO environment by the indoor environmental simulation using the ray-tracing technique. |
