Summary: 
In this paper, we investigate the resource and power allocation schemes of partial block multi-carrier code division multiple access (PB/MC-CDMA) systems. In our proposed scheme, we manage transmit power depending on each user's channel state information (CSI). The objective is to maximize the average bit error ratio (BER) performance with minimal influence from the received signal-to-interference ratio (SIR), both of which are closely related to transmit power. To obtain additional performance improvement, our frequency band rearrangement scheme follows the transmit power control (TPC) process. We evaluate the performance of the proposed scheme using simulations. The results show that the proposed system provides superior performance compared to those of conventional systems.
