چکیده
An outline of the analysisof thestochastic dynamics of the blind adaptation of deckion fcedbadr equalizers (DFEs) operating on noiselm, binary commuuication channels is presented. The general mech.anism whereby the blind adaptation is flawed in the sense that thae Bdst attraction points in parmeter space which lead to unequalLed systems is detined and c l d e d with an exnmple. This bchaviour is predicted by defining the implicit a m r function whose gradient d&es the direction of the drift of the adapting pclramctcm. Thin snafysia is complnnented by an averaging ~ a l y s i s which a h graphically illustrate the drift medrsnism.

On the Convergence of Blind Over-Sampled Decision Feedback Equalizers
Decision Feedback Equalizers (DFEs) efficiently reduce the effect of Inter Symbol Interference (ISI). Their blind (or Decision-Directed) adaptation may converge to so-called degenerated solutions when signal at the equalizer output is independent of its input. One of the solution to this problem is to use Predictive Decision Feedback Equalizer (PDFE), another solution proposed consists in impos...

The cost function of constant modulus algorithm (CMA) is simplified to meet second norm form, and the blind equalizer can use recurrent least squares (RLS) algorithm to update the weights. Considering the underwater acoustic channel is usually nonlinear, decision feedback equalizer is used as the blind equalizer. According to the simplified cost function of CMA, the weights of forward part and ...

متن کاملA blind adaptation algorithm for decision feedback equalization for dual-mode CAP-QAM reception
− This paper introduces an algorithm for blind adaptation of decision feedback equalizers (DFE), which is applied for equalization in the passband domain. The transmission scheme, which is assumed to be unknown at the receiver side, can either be carrierless amplitude/phase (CAP) modulation or quadrature amplitude modulation (QAM). As the input signal of the passband equalizer is real-valued, t...
متن کاملBlind Iterative Decision Feedback Equalizers for Block Qam Transmission Systems
A novel blind initialization procedure for iterative decision feedback equalizers in block-based transmission systems is proposed and investigated. It relies on an initial stage using Regalia’s blockbased Constant Modulus iterative algorithm for the blind computation of a linear equalizer; then a switch to decision feedback mode is performed. It is shown how the building blocks of the decision ...
