Receive signal processing for space-time coded transmissions in the presence of channel estimation errors

The paper deals with space-time-coded transmissions sence of channel estimation errors. A simple on model is described which gives insight into the tions between space-time block coding schemes and l concept of spreading. On the basis of this model, lgebraic space-time (DAST) block codes are taken as an or maximum ratio combing and equal gain combining n, that in case of channel estimation errors suboptimum at the receiving side might outperform optimum ones. atical equivalence between DAST and multicarrier ion multiplexing as a by-product of the modelling is ssed.
