Abstract :
This paper deals with downlink space-time processing for FDD (frequency division duplex) radiocommunication systems whose base stations are equipped with antenna arrays. We show how space-time filters can be appropriately designed for the downlink in order to both combat co-channel interference and reduce fading effects. These filters, which can be estimated from uplink data only, are an extension of previous schemes which considered only space processing for the downlink
