Ultra Low Density Spread Transmission

Abstract

Ultra low density spread (ULDS) transmission scheme, allowing simultaneous and efficient usage of given time-frequency resources by multiple users, is presented and evaluated. The scheme is based on the special sets of LDS signatures that eliminate the need for iterative multi-user detector (MUD) in the receiver and dramatically improves reception… (More)
