Abstract  

In this paper the base band CDMA (Code Division Multiple Access) modem hardware design is described. The implemented design has been developed within the University research project sponsored by ASI (Italian Space Agency) in collaboration with CNIT (National Interuniversity Consortium for Telecommunications) “Integration of Multimedia Services on Satellite Connected Heterogeneous Networks”. The aim of this project is to connect more University sites in order to establish videoconferencing, data exchange and other multimedia high bit rate communications. So to have this link, we have designed an high performance modem, able to grant a full duplex data flow. The challenge is that to implement a CDMA modem, developing both the
hardware platform and the software performing the data processing. Obviously, the most innovative idea is to implement multi user detection algorithms at the reception, where it is required an high processing capacity due to the large quantity of operations needed to reject the other users interference, and, to enhance the performance of the user to be detected.
