Channel decoding with a Bayesian equalizer [PDF]
2010 IEEE International Symposium on Information Theory, 2010 Low-density parity-check (LPDC) decoders assume the channel estate information (CSI) is known and they have the true a posteriori probability (APP) for each transmitted bit. But in most cases of interest, the CSI needs to be estimated with the help of a short training sequence and the LDPC decoder has to decode the received word using faulty APP ...

A Gaussian Mixture Approach to Blind Equalization of Block-Oriented Wireless Communications
EURASIP Journal on Advances in Signal Processing, 2010 We consider blind equalization for block transmissions over the frequency selective Rayleigh fading channel. In the absence of pilot symbols, the receiver must be able to perform joint equalization and blind channel identification.
