Structures and performances of several adaptive Kalman equalizers

The paper revisits the problem of equalization with an IIR filter. The use of the discrete Kalman observer is adopted to perform the IIR equalization and to circumvent the minimum phase spectral factorization. A unified study of adaptive equalizers based on the Kalman observer is presented, a novel adaptive Kalman equalizer scheme is discussed and finally, a performance comparison is given by computer simulations.
