摘要
This work investigates iterative architectures for coded transmission over multiple input multiple output channels in the presence of channel uncertainty. Robust receivers that are less sensitive to the uncertainty are designed. The nature of iterative algorithms is especially suited to iterative decoding and channel estimation (ID&CE), which is a widely accepted means of dealing with imperfections in channel state information. ID&CE re-estimates the channel in each iteration to deal with the uncertainty. The derived robust algorithm can be combined with ID&CE to yield significant performance gains as demonstrated by the simulation results.
