In this paper, we consider spatial-division multiple-access (SDMA) systems with one base station with multiple antennae and a number of single antenna mobiles under noisy limited CSIT feedback. We propose a robust noisy limited feedback design for SDMA systems. Furthermore, we show that despite the noisy feedback, the average system goodput scales as O(n T (1-?)/n T -1(C fb  -log 2 (N n ))) and O(n T ·log 2  P) in the interference limited regime (C fb   T  - 1) log 2  P + log 2  N n ) and noise-limited regime respectively.
