Abstract--- Capacity of cellular CDMA applying interference cancellation is calculated for the uplink (reverse link) in the presence of AWGN. Both conventional demodulation and decorrelation are investigated as preprocessing unit to interference cancellation. Taking into account the path loss in a cellular system, CDMA applying interference cancellation shows a substantial difference in power efficiency, whether receive or transmit power is considered. This is in contrast to orthogonal multiple--access techniques, like TDMA and FDMA. If the comparison is based on transmit power, which is more reasonable, CDMA outperforms orthogonal multiple--access schemes., |
