Space-Time Coding over Real-World MIMO Channels with No Transmit Channel Knowledge

As highlighted in the previous chapters, the performance of space-time codes may be severely affected by the scattering richness, the array design or the presence of coherent components. Since a large variety of propagation conditions is likely to be encountered in practice, there is an obvious appeal to design codes that are robust with respect to all possible propagation conditions.

This is the objective of this Chapter, assuming that the transmitter has no prior channel knowledge. In a sense, the criteria described hereafter may be thought of as being to correlated Rayleigh/Ricean channels what the rank/determinant criteria of Chapter 6 are to i.i.d. ...
