Abstract

The Infostation concept is proposed for fourth generation cellular communications to provide very low cost data transfer. It provides non-ubiquitous coverage and very high data rates for users within small, isolated coverage areas by means of adaptive transmission. We propose a transmission scheme for infostations based on multi-carrier CDMA (MC-CDMA). The proposed system performs adaptive transmission by changing spreading code allocation and using adaptive modulation. In the receiver we propose to use successive interference cancellation (SIC), which decodes the most reliable symbols first. Approximate analytic and simulated results for bit error rate are given for a Rice Infostation channel. Transmission rates for the two user case under two proposed resource allocation policies are shown.
