Abstract：Firstly, the uplink capacity of CDMA system, in multi-path fading channels with single-user-detection and multi-user detection, is analyzed in this paper. The uplink capacity comparison between LS code and Walsh code is discussed for the above-mentioned receivers (multi-user detector, single-user detector) in multi-path fading channels. The result shows the capacities of LS code and Walsh code are approximately the same when the multi-user detector is adopted. However, the capacity of LS code is much higher than Walsh code in condition that single-user detector is applied.
