- Abstract
- In this letter, we propose a multicarrier code-division multiple-access (MC-CDMA) system employing an antenna array at the base station, and analyze the performance of the MC-CDMA system in a fading channel. An optimal beamformer not requiring explicit direction of arrival estimation or training signals is derived for the MC-CDMA system in the reverse link, and is shown to reduce interferences from other users significantly, thus increasing the system's user capacity. Also, it is shown that the MC-CDMA approach can achieve better performance than the direct-sequence CDMA approach when both approaches employ the code filtering technique for antenna array.
