Capacity with MRC-based macrodiversity in CDMA distributed antenna systems
Lin Dai, Shidong Zhou, Yan Yao · 2003
We analyze the effect of MRC-based macrodiversity on the reverse-link and forward-link capacity in CDMA distributed antenna systems. A detailed analytical model is presented and exact outage probability expressions are derived. Our investigation shows that on the reverse link, with macrodiversity the interference can be suppressed greatly, which leads to a significant increase of capacity. However, on the forward-link, we prove that if simulcasting is used in CDMA distributed antenna systems, the forward-link capacity cannot increase with macrodiversity whatever power allocation scheme is adopted.
