Abstract

The purpose of this letter is to examine channel power assignment for multiuser direct sequence/code division multiple access (DS/CDMA) uplinks. The channels under consideration are pilot channels and data channels. A multiuser detector is also included. The pilot channel estimates are used for multiple access interference (MAI) regeneration, as well as for data channel detection. Simulation results allowed us to pinpoint optimum pilot-to-data channel power ratios (PDR's) for the best bit error rate (BER) performance. In addition, the optimum PDR's of the receivers with the multiuser detector are high compared with those of conventional receivers without the multiuser 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 multiuser detector.
