Using infrared LED to achieve the uplink transmission.
In the MxN system, ADR technology is applied to both the receiver and transmitter. Each user have L LEDs, but only one LED will be activated. In that case, this paper proposed a method called SFRA &GA to find the optimal strategy for the users. Moreover, it conducts an experiment to compare the performance of SFRA and ST.

This paper is good, because it strongly concerned multi-user uplink communication. The background and the system setup is very useful for my own research. But I feel a little upset about the parameters as this paper only uses SINR to evaluate the system performance.
