  Abstract

The purpose of our paper is to examine channel power assignment for multi-user direct sequence/code division multiple access (DS/CDMA) up-links. The channels under consideration are pilot channels and data channels. A multi-user detector is also included. The pilot channel estimates are used for multiple access interference (MAl) regeneration, as well as for data channel detection. Simulation results allowed us to pinpoint optimum pilot-to-data channel power ratios (PDRs) for the best bit error rate (BER) performance. In addition, the optimum PORs of the receivers with the multi-user detector are high compared with those of conventional receivers without the multi-user detector. This study may prove helpful in the effort to optimize the channel power assignment for channel estimation and coherent detection of systems with the multi-user detector.
