In DS-CDMA high speed wireless signal transmissions, a transmission performance degrades due to a frequency selective fading. The use of frequency-domain equalization (FDE) can significantly improve the transmission performance. However, local average received signal power slowly varies due to distance-dependent path loss and shadowing loss according to the movement of a mobile user. This variation causes the performance degradation particularly when a user is located close to the cell edge. Site diversity with FDE can improve the transmission performance. Space-time coded transmit diversity (STTD) is also effective to improve the performance. In this paper, we present downlink site diversity with FDE applied STTD for DS-CDMA cellular systems. The DS-CDMA downlink capacity is evaluated by computer simulation. |
