This contribution is on the framework of a wireless network with multiple interfering transmitter-receiver pairs. We study the case where there is no direct communication channel between the multiple transmitters and the system is completely distributed (in terms of information available and decision making). Exchanging local channel state information (CSI) among the transmitters is one solution to the problem of improving the efficiency of the network. We introduce a novel power modulation scheme that facilitates reliable exchange of local CSI through the signal power strength assuming feedback of received signal strength indicator from each receiver to its transmitter. Numerical results demonstrate the value of our approach.
