Abstract :
We developed the forward channel model for a DS-CDMA cellular system operating in a slow-flat Nakagami-fading and lognormal-shadowing environment. Forward error correction is integrated into the analysis by applying convolution encoding with soft-decision decoding. The worst-case probability of bit error for a mobile user at the edge of the center cell of a seven-cell cluster is developed using Gaussian approximation. We also incorporate user distribution and power control and antenna sectoring into our analysis.
