This paper proposes a staggered superposed transmission scheme of narrow band limited spread spectrum multiple access (SSMA) signals and multicarrier high‐ speed signals. to lessen degradation due to mutual interference between SSMA signals and multicarrier high‐ speed signals, SSMA signals are set between two high‐ speed signal channels. Moreover, a band‐limitation filter in the transmission side and an interference‐suppression filter in the receiving side whose bandwidths are narrower than Nyquist bandwidth of spreading code chip‐rate are employed. the proposed scheme decreases SSMA signal transmission power and increases the number of SSMA channels.
