N2 - The rapid development of commercial cellular direct-sequence code division multiple access (DS-CDMA) systems, has raised interest in their information theoretic analysis. However, most analyses so far focus on a single-cell scenario in which all users are equivalently treated by the cell-site processor, and the detrimental effect of adjacent cell interference on system performance is not considered. Seminal results and observations, for a single cell DS-CDMA system, were recently published in [l] and [2] (see also references therein). These works explicitly relate to CDMA systems with random spreading sequences, and address asymptotic conditions in which both the number of users and the processing gain go to infinity, while their ratio (denoted p and referred to also as the "system load") is kept arbitrarily fixed. The purpose of this work is to extend the above results to multi-cell systems.
