In this thesis, the performance of the forward channel of a DS-CDMA cellular system operating in a Nakagami-fading, Lognormal-shadowing environment is analyzed. Given the upper bound of bit error probability with FEC and including all the appropriate losses and interference terms, the bit error probability in various fading and Lognormal shadowing conditions is computed in two ways; firstly, by setting up a statistical model and secondly, by Monte Carlo simulations. The results predicted by the two methods take into account that the intended user is located at the corner of the hexagon of a seven-cell structure (worst case scenario). Furthermore, in order to obtain more realistic and accurate results, the user's distribution is incorporated in the cell and finally fast power control is applied to overcome the Lognormal shadowing effects.
