An information theoretic analysis of multiple antenna systems shows that the possible gain due to transmitter-sided channel knowledge is usually small for uncorrelated fading. However, it is not obvious how these results translate to real-world transmission strategies. Thus, in this paper the error performance of adaptive bit and power loading with perfect(More)
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(More)
