Improving Downlink Performance in Cellular Radio Communications

In cellular communications there are two primary communication links between the cell’s central basestation and the users, the uplink (or reverse link) and the downlink (or forward link). The former refers to the flow of information from the users to the basestation, and is a problem which has been and is still today the subject of much debate. The downlink, however, receives less attention, since to some extent it is a simpler problem. The main reason being the inherent synchronism between the users signals. In a single-cell scenario we only have the problem of transmitting a single signal containing the information for all the users to the collection of users located within the cell’s boundary. In this work we restrict ourselves to this situation.
