| Abstract(in English) | In frequency domain phase rotated/multi-carrier code division multiple access (PR/MC-CDMA), users are multiplexed using user-specific frequency domain phase rotation. To increase the data rate, the authors recently proposed a signal detection method for MC-CDMA with space division multiplexing (SDM), in which each path is treated as a virtual receive antenna. Code mutlipexing can be used to further increase the data rate (or increase the number of accomodated users) in the system, but the inter-code interference (ICI) degrades the downlink transmission performance and the multi-access interference (MAI)) degrades the uplink transmission performance of PR/MC-CDMA. Multiple users can be mapped onto phase rotation and different spreading codes. Furthermore, multiple data symbols of each user is spatially multiplexed. In this paper, an iterative interference cancellation (IC) is introduced to frequency domain PR/MC-CDMA SDM system. The impacts of symbol mapping strategy (phase, code, space) and the iterative IC on the performance are investigated by computer simulation. |
