Abstract
This paper investigates the behavior of a CDMA system in conditions of underground propagation collaborated with QPSK modulated signals. The antennas contained in boreholes were modeled as transmission lines. We studied the influence of the impurities of the propagation medium and also presented the role of the dimensions of the drilled cavity that the antennas are contained in. We also investigated the noise introduced by linear quantization. Following the simulation results several conclusions can be drawn in the last chapter.
