Using Nonlinear Filter for Adaptive Blind Channel Equalization

InterSymbol Interference (ISI) of the radio propagation through channels is a major factor that limits the performance of mobile communication systems and can be compensated by equalization. One of the basic groups of equalizers is based on linear algorithms. In this paper, we propose the other method based on Hammerstein filter as a nonlinear memoryless blind equalizer. We have compared these ...

Adaptive Blind Sparse-Channel Equalization

In this article, a fractional-norm constrained blind adaptive algorithm is presented for sparse channel equalization. In essence, the algorithm improves on the minimisation of the constant modulus (CM) criteria by adding a sparsity inducing lp-norm penalty. Simulation results demonstrate that the proposed regularised equalizer exploits the inherent channel sparsity effectively and exhibits fast...

Blind Adaptive Channel Equalization with Performance Analysis

A new adaptive multiple-shift correlation (MSC)-based blind channel equalizer (BCE) for multiple FIR channels is proposed. The performance of theMSC-based BCE under channel order mismatches due to small head and tail channel coefficient is investigated. The performance degradation is a function of the optimal output SINR, the optimal output power, and the control vector. This paper also propose...
