Abstract

Joint transmitter/receiver optimization is studied for a Direct-Sequence (DS)-Code Division Multiple Access (CDMA) system with multipath. Two optimization problems are considered corresponding to voice and data services, respectively: (i) Minimize the average transmitted power subject to a received Signal-to-Interference Plus Noise (SINR) constraint, and (ii) Maximize the data rate subject to a transmitted power constraint. In the latter case, the rate is maximized by introducing multiple optimized spreading codes. Numerical results are presented which compare achievable rates with multi-code optimization vs. single-code optimization in the presence of fixed random interferers.
