Spectral sharing in multi-system environments via multi-carrier CDMA
Seyed A. Reza Zekavat, C.R. Nassar · 2004
In this work, the authors introduce the concept of spectral sharing in multi-system environments by application of MC-CDMA technology. The proposed MC-CDMA system supports spectral sharing via dynamic carrier allocation: the orthogonal carriers that make up a transmit signal are borrowed/shared between multiple systems. The resulting system not only supports increased spectral efficiency, but simulations indicate improved BER performance as well. It is hoped that this exploration will serve as a useful beginning in the emergence of a highly efficient spectral exchange.
