  abstract={We propose the use of multistratum space-time codes (MSSTC) for the asynchronous uplink of broadband MIMO-CDMA systems. This transmission scheme, originally proposed for single-user systems and flat fading channels, combines the benefits of both space-time block codes and multilayer transmission, i.e. it exploits transmit diversity and simultaneously enables high data rates with reasonable decoding complexity. Though the full potential of multistratum codes can only be achieved by using adaptive channel coding, we show by simulation results that they are a promising approach even in the uncoded case.},
