Abstract :
This work considers a network with K transmitters and receivers, where the transmit-receive association is not predetermined. It is thus an interference network where the pairing between transmitters and receivers can be optimized to improve performance. This model is designed to represent a cellular system where each transmitter (mobile) is attempting to determine the best receiver (base-station) to connect to so as to maximize throughput. It is shown that in the two transmit-receive case, it is always better for a user to communicate with the ¿stronger¿ base station, for a network with K > 2 transmitters and receivers, there exists a range of channel realizations for which connecting mobiles with a ¿weaker¿ base station results in a higher network throughput than connecting to the base-station with the ¿stronger¿ signal.
