| Abstract(in English) | Distributed antenna network (DAN), in which many antennas are spatially distributed in each radio cell, can mitigate the impacts of the propagation path loss, the shadowing loss, and the frequency-selective multipath fading and achieves a good transmission performance in the entire radio cell. The multiple access (MA) has two types: orthogonal MA and non-orthogonal MA. The time division multiple access (TDMA) and frequency division multiple access (FDMA), both of which are the type of orthogonal MA, require a complex channel assignment. To alleviate such a complexity problem, we consider the code division multiple access (CDMA) which is the type of non-orthogonal MA. In this paper, we investigate the uplink capacity of DAN using direct-sequence CDMA (DS-CDMA) with joint minimum mean square error based frequency domain-equalization (MMSE-FDE)/antenna diversity. It is shown by the computer simulation that DS-CDMA DAN reduces the required transmit power and obtains larger uplink capacity than conventional centralized antenna network (CAN) using DS-CDMA, where multiple antennas are co-located at a base station (BS) in the cell center. |
