Closed loop adaptive modulation systems rely on a feedback channel to receive channel state information from the users and set according to it the appropriate modulation index. In [1] three joint adaptive modulation and combining scheduling schemes are suggested to manage the wireless resource between many users in a multiuser diversity environment. The assumption that was made in that work is that the feedback channel is error free. In this work, we try to investigate the new system performance when assuming the existence of errors in the feedback channel which is closest to the real case.
