| description | Background. Many modern communication-systems work on channels with intersymbol interference. Therefore comparative analysis of elementwise reception-algorithms is topical by work in such channels. Aim. The Aim of this work is qualitative properties of suboptimal demodulators on maximum-likelihood-rule based and demodulators on linear equalizers based. Methods. The method of simulation computer modeling was used for acquisition these qualitative properties. By modeling the models of one-path as well as multi-path channels by how specific keying rate (faster than Nyquist-rate) were used. Results. Optimal and suboptimal sorting-algorithms as well as algorithms on linear equalizer based were consider. The qualitative properties on simulation computer modeling based were received. Conclusion. The results of simulation modeling reveal, what decision feed-back noise immunity is improved, in spite of error extension. The demodulators, on linear equalizer based, have comparable qualitative properties with sorting demodulators. Herewith the positive impact of decision feed-back was observed. |
