摘要：

In this letter, we propose an OFDMA/CDM-based cellular system. which accommodates users in different frequency bands and multiplexes user data symbols with frequency domain spreading. The proposed system utilizes random codes to discriminate between cells and adopts the pre-equalization to enhance the performance. An efficient power allocation scheme is suggested for cellular applications with a transmit power constraint. In particular, the validity of the OFDMA/CDM-based cellular system is examined, by investigating its performance as a function of the number of multiplexed data symbols at different locations.
