Abstract

In this paper, the problem of space only downlink processing for FDD (Frequency Division Duplex) radio-communication systems is considered. It is shown that using criterions based on average C/I, one can avoid DOA estimation and deduce these criterions at downlink frequency from their equivalent at uplink frequency, under sonic assumptions about array topology. Moreover, here, we introduce a more generic approach than the former one. denoted as pattern synthesis.
