A max-min fair approach to optimize the CDMA capacity region

Abstract

The max-min fairness idea is applied to optimize the CDMA capacity region. For any given signal set, a fair rate-allocation algorithm is specified. The notion of fair capacity is introduced and a signal design algorithm is proposed that produces signal sets with near-maximum fair capacity under (a) optimum decoding and (b) suboptimal decoding based on MMSE filtering and successive decoding, when there is sufficient bandwidth.
