Abstract

We analyze the performance of a Direct Sequence (DS)-Code Division Multiple Access (CDMA) link with limited feedback in the presence of random interfers. We evaluate the performance of a Reduced-Rank (RR) signature optimization scheme with a linear Minimum Mean Squared Error (MMSE) receiver, and subsequently account for the feedback quantization error. The performance is compared with a random vector quantization scheme for signature selection, which gives an upper bound on large system performance.
