Abstract

2-dimensional (2D) block spread direct sequence-code division multiple access (DS-CDMA) allows uplink mutli-rate/mutli-connection transmissions without causing a serious multi-access Interference (MAI) in the presence of a frequency-selective fading channel. However, in a cellular system, the intercell interference remains. The site selection diversity (SSD) can be used to reduce the inter-cell interference and increase the uplink capacity. Furthermore, transmit power control (TPC) is necessary to combat the near-far problem. In this paper, we discuss the impact of SSD and TPC on the uplink capacity of 2D block spread DS-CDMA and compare it with those of conventional DS-CDMA and 1D block spread DS-CDMA.
