Abstract

In this paper, we consider spatial-division multipleaccess (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-ε)n _T-1(C_fb -log₂(N_n)))and O(n _T.log₂ P) in the interference limited regime (C _fb < (n_T - 1) log₂ P + log₂ N_n) and noise-limited regime respectively.
