The decision-feedback equalizer optimization for Gaussian noise

Grzybowski A., Kisilewicz J. W.

Journal of Theoretical and Applied Computer Science

2014

Vol. 8, nr 4

5-12

The new method of decision-feedback parameters optimization for intersymbol interference equalizers is described in this paper. The error extension phenomena is well known and investigated in the decision feedback equalizers in data transmission. The existing coefficient in decision feedback depends on the receive decision risk qualification. There is proved the bit error probability can be decreased by this method for any channel with single interference sample and small Gaussian noise. The experimental results are presented for chosen type channels. The dependences of optimal feedback parameters on channel interference sample and on noise power are presented too.

Optimal erasures in decision-feedback equalization for the Gaussian noise

Kisilewicz J. W., Grzybowski A.

International Journal of Applied Mathematics and Computer Science

2006

Vol. 16, no 1

147-154

A new method of optimizing decision feedback parameters for intersymbol interference equalizers is described. The coefficient existing in the decision feedback loop depends on risk qualification of the received decision. We prove that bit error probability can be decreased with this method for any channel with a single interference sample and small Gaussian noise. Experimental results are presented for selected channels. The dependences of optimal feedback parameters on channel interference samples and noise power are presented, too.
