In this paper, we determine expressions for the bit error rate (BER) performance and for the signal to interference ratio (SIR) of a direct-sequence code division multiple access (DS-CDMA) system over the space-time hyperbolic channel model for a macrocell environment. A simplified expression based on the improved Gaussian approximation (SEIGA) is used to evaluate the BER and the SIR in a wideband multipath channel. The multipath power delay profiles (PDP), which are generated by this channel have been used to evaluate the BER and the SIR for the DS-CDMA. The performance of DS-CDMA over the hyperbolic channel model is examined in different propagation scenarios (i.e. urban scenario, shadowed urban, and free space scenario) and with varying numbers of multipath components.
