Achievable Rates using Practical Decoders for Fading Channels with Estimated Channel State Information

Abstract:

In wireless communications channel state information (CSI) is either unavailable or imprecise due to the random and time-varying behavior of the channel. In this thesis, the impact of imperfect CSI at the receiver on the achievable rates is investigated. Optimal decoding with imperfect CSI often yields complex decoders which cannot be employed in practice. Therefore, the mismatch capacity, which represents an information theoretic measure to specify the achievable rates with a fixed, possibly suboptimal, decoder, is introduced. Finally, a short example is given to show how the mismatch capacity can be used to analyse the impact of imperfect CSI.
