Space-time block coding for channels with intersymbol interference

The downlink of many wireless communication systems can be a MISO channel. An important problem for a MISO channel is how to code across space and time to obtain the same ML receiver as for the corresponding SIMO channel. For fiat fading channels, space-time block coding (STBC) is a recent breakthrough solution to this problem. STBC has been generalized to channels with intersymbol interference (ISI) for the case of two transmit antennas and one receive antenna. In this paper we first revisit the generalized STBC scheme of et al. (2000), and show that it has the same appealing properties as the standard STBC for flat fading channels. Then we go on to present an extension of the scheme in Lindskog to ISI channels with any number of transmit and receive antennas.
