Abstract

The application of various space-time block coding (STBC) schemes in DS-CDMA systems is considered. In particular, the bit-error-rate (BER) performance of orthogonal, quasi-orthogonal, and linear dispersion codes in a number of system configurations is compared. Simulation results show that significant improvements in the BER performance can be achieved by integrating STBC into DS-CDMA systems. These performance improvements are found to be related to the diversity order offered by a given STBC scheme, the order of a modulation scheme, and type of the receiver.
