This work proposes a new multi-user detection scheme based on ubiquitous antennas for co-channel heterogeneous radio signals, which are generated from different kinds of wireless services in the same frequency band. The ubiquitous antenna system is composed of multiple radio base stations (RBSs), the central control station (CCS) and radio-on-fiber (RoF) link. Computer simulation results show that the multi-user detector employing the minimum mean square error (MMSE) based combiner and the successive interference canceller (SIC) in combination can achieve the coexistence of coded orthogonal frequency division multiplexing (COFDM) and direct sequence spread spectrum (DSSS) signals.
