Dears,
I want to increase the number of antennas at the base station up to 8 in Vienna LTE-A Uplink Link Level Simulator. Any idea is beneficial for me.
I am grateful for your reply. I have tried to increase LTE_params.BS_config.nRX, but I have found that the max no. of antennas is 4, after 4 the simulator does not work, is it possible to increase LTE_params.BS_config.nRX to be 8 antennas? and what is the modification in the code will be if it is possible ?
In fact, I want to use 8 antennas at the base station with any mode, for instance, 8 antennas with mode 1 or mode 4 or mode 9. is that possible just with changing the settings of parameters or it requires some code modification.Please, I am looking forward to your feedback.
please be aware that there is no transmission mode 9 available in the LTE-A uplink LL simulator. There are mode 1, single transmit antenna, and mode 4, closed loop spatial multiplexing, currently available. In either of these modes, modifications in the code are necessary to enable for Nrx=8. I will have a look into that.
For mode 4 a number of 8 transmit antennas is actually working without and modification. For mode 1 there is a very small modification necessary:
In LTE_UL_RX.m change line 144 from
the investigation of RRH deployment aspects is more of an system level simulation task and therefore unfortunately not easy to include in our link level uplink simulator.
