Abstract
We are developing a multi-cell system-level simulator using a distributed computing environment. The multi-cell system-level simulator enables us to asses the gains of various multiple input multiple output (MIMO) transmission and receiving techniques such as:
- Codebook based transmit beamforming (according to LTE specifications),
- Interference aware multi user scheduling Beyond 3G-LTE
- Receivers such as maximum ratio and optimum combining,
- Coordinated MultiPoint CoMP transmission / reception.
It supports the spatial channel model extension (SCME), WINNER II channel models and WINNER II ITU channel models.
Technical Discussion
