Blind equalisation of IIR channels using hidden Markov models
Vikram Krishnamurthy, Subhrakanti Dey, J.P. LeBlanc · 2002
A computationally inexpensive suboptimal blind equalization algorithm is presented for noisy IIR channels. It is based on combining a recursive hidden Markov model (HMM) estimator with a relaxed SPR (strictly positive real) extended least squares (ELS) scheme. Simulation studies show that the algorithm yields satisfactory results.>
