Abstract

A randomly spread direct sequence code division multiple access (DS-CDMA) multi-cell system operating in flat fading is considered. The model adheres to Wyner's (1994) infinite linear cellarray setting, where only adjacent-cell interference is present, and characterized by a single parameter 0 ≤ α ≤ 1. Users are assumed to employ equal rates and transmit powers. The receiver ranks the intra-cell users according to their received powers, and decodes only the subset that can be reliably decoded. Confining the discussion to asymptotic analysis (in terms of number of users and processing gain), we study four multiuser detection strategies, differing in the amount and type of information available to the receiver with respect to (both intra-cell and out of-cell) interfering users. The total capacities under outage constraint, derived as functions of the fraction of users that cannot be reliably decoded (equivalent to the "outage probability"), are analyzed and compared.
