Robust Estimation in Rayleigh Fading Channels Under Bounded Channel Uncertainties
We investigate channel equalization for Rayleigh fading channels under
bounded channel uncertainties. We analyze three robust methods to estimate an
unknown signal transmitted through a Rayleigh fading channel, where we avoid
directly tuning the equalizer parameters to the available inaccurate channel
information. These methods are based on minimizing certain mean-square error
criteria that incorporate the channel uncertainties into the problem
formulations. We present closed-form solutions to the channel equalization
problems for each method and for both zero mean and nonzero mean signals. We
illustrate the performances of the equalization methods through simulations
