Abstract:

An opportunistic feedback protocol has been proposed in the literature to achieve multiuser diversity for the downlink transmission of a multiuser wireless system. In this letter, through theoretical analysis and extensive simulations, it is shown that the capture effect can have a significant impact on system throughput. It is also shown that, to achieve optimal throughput, the number of minislots used for opportunistically finding a user in the protocol should not be too large due to the overhead induced by the control packets. © 2006 IEEE.
