Block based Partial update NLMS Algorithm for Adaptive Decision Feedback Equalization

Bayesian/decision-feedback algorithm for blind adaptive equalization

Properties of an adaptive feedback equalization algorithm.

This paper describes a new approach to feedback equalization for hearing aids. The method involves the use of an adaptive algorithm that estimates and tracks the characteristic of the hearing aid feedback path. The algorithm is described and the results of simulation studies and bench testing are presented.

A fast Newton multichannel algorithm for decision feedback equalization

327 neither TI'* nor a* would be computed more than once. In addition, the complexity of O(1<2h+'r2) MAD for the overall backward recursion algorithm can be obtained. Please note that in the course of performing the time backward update recursions from 80 to 79 for all possible subset autoregressions, only the parameter matrices and the necessary IC'* and (I* at 80 are required to acquire all p...

Adaptive Multiuser Decision Feedback Detection using Erasure Algorithm based Partial Parallel Interference Cancellation

In this paper, adaptive decision feedback detector (ADFD) based on parallel interference cancellation (PIC) approach is proposed for code division multiple access (CDMA) wireless systems, which not only suppresses the intra-cell interference but also cancels the inter-cell interference. We incorporate the erasure algorithm based soft-slicer (E-slicer) to control the error propagation effect in ...

Adaptive decision feedback equalization: can you skip the training period?

This paper presents a novel unsupervised (blind) adaptive decision feedback equalizer (DFE). It can be thought of as the cascade of four devices, whose main components are a purely recursive filter (R) and a transversal filter (T ): Its major feature is the ability to deal with severe quickly timevarying channels, unlike the conventional adaptive DFE. This result is obtained by allowing the new...
