An efficient method for data exchange using network coding and narrowband multiuser detection

Abstract

The proposed technique applies to full duplex mobile-to-mobile pair wise communication via a common centralized node such as a base station or satellite. In the uplink, a multiuser receiver is employed using Turbo Code Division Multiple Access (TCDMA) optimized for two narrowband bursts generated by the two users. In the downlink, a single burst using network coding is addressed to both users. Applying the proposed technique to mobile-to-mobile applications, the radio resources are used very efficiently since the network capacity is almost doubled and the radio resource management is simplified so that message delivery time is halved.
