| Title: | CAPACITY OF A DOWNLINK MC-CDMA MULTI-CELL NETWORK | ||
| Authors: | Mérouane Debbah; Institut Eurécom | ||
| Abstract: | In this paper, a new approach to determine the number of cells for a given environment and coverage area is provided. Base stations are located on a square grid of surface $A$. Each base station covers an area of size $\alpha A$. The goal is to determine the optimal parameter $\alpha$ in the case of a downlink MC-CDMA scheme where each user is equipped with a matched filter. Two types of codes are studied: random i.i.d and orthogonal (per cell) codes. We show that in the absence of path loss, the cellular architecture depends only on the second and fourth moment of the channel. | ||
