The performance of reverse-link macrodiversity in CDMA distributed antenna (DA) systems with imperfect channel estimation is analyzed by taking the effect of multi-path fading environment into account. A detailed multi-access model with MRC-based multi-path micro diversity and multi-antenna macrodiversity is presented and exact reverse-link E b/I0 expression is derived. The investigation shows that when multipath fading and channel estimation errors occur, for the reverse-link of CDMA DA systems, the Eb/I0 performance degrades and the macrodiversity gains diminish more rapidly in comparison with the results obtained based on the ideal assumption. Furthermore, it is shown that, on the reverse-link, the conventional solution recommended in most of previous studies that the number of remote antennas per "virtual cell" set to four is no longer cost-effective in such an imperfect environment
