LTE system level simulation
4.0
Application background & nbsp; the simulator can share LTE SISO and MIMO channels and use open-loop spatial multiplexing and transmission diversity in downlink performance evaluation. The model is based on the physical layer postequalization SINR, and provides simulated pre calculated & nbsp; fading parameters to represent each individual interference term. In this structure, the fading parameters are pre generated offline, which greatly reduces the complexity of computation. Key technology the main file of LTE link level simulation is LTE_ sim_ main。 M. Although you may run simulation normally through a batch file such as LTE_ sim_ launcher。 M. It performs the following tasks: · load the selection profile. See the configuration parameters listed in Section 3. Perform LTE_ sim_ Main M is the main simulation file.

Application background DBPA - Distance Based Power Alocation Algorithm
in this progarm mobiles are uniformally distributed within the cell to allow varing power for the Downlink, each mobile then transmitte according to the recevied power from base station.
Key Technology
MSPC - Multi-Step SIR Power Control Method, Algorithm
in this progarm let mobiles compare SIR from base station with SIR threshold in order to give feedback to base station on the state of the Downlink. Mobiles are uniformaly distributed within the cell, and link gain ognormaly distributed for each mobile,when the SIR observed is below SIR threshold, then mobile sends an increament command to base station and when SIR observed is above SIR threshold decreament command is sent.
