초록
In this paper, we investigate performance of OFDM employing macrodiversity selection on a shadowed multipath channel to reduce the effects of long-term shadowing. Three different situations are considered： independent shadowing with equidistant ports, independent shadowing with non-equidistant ports, and correlated shadowing. Numerical results show that OFDM performance is improved as the number of macrodiversity ports increases. In the situation where the user is much closer to certain port(s), performance becomes worse compared to that of the equidistant situation. In addition, as the correlation increases among the ports, the advantage of macrodiversity is reduced.
