LMMSE turbo equalization based on factor graphs
Abstract--In this paper, a vector-form factor graph representation is derived for intersymbol interference (ISI) channels. The resultant graphs have a tree-structure that avoids th...

Pre-Equalization and Precoding Design for Frequency-Selective Fading Channels
— In this paper, we consider the joint transmitter and receiver design problem based on a novel approximate maximum likelihood decision feedback equalizer (A-ML-DFE) over frequen...

Single-carrier systems with MMSE linear equalizers: Performance degradation due to channel and CFO estimation errors
We assess the impact of the channel and carrier frequency offset (CFO) estimation errors on the performance of singlecarrier systems with MMSE linear equalizers. Performance degra...

A family of algorithms for blind equalization of QAM signals
We propose blind equalization algorithms that perform similarly to supervised ones, independently of the QAM order. They converge approximately to the Wiener solution, which gener...

On L-valued Equalites on the L-powersets of Many-valued Sets
The research in the field of the so called Fuzzy Mathematics can be conditionally devided into two mainstreams: the first one emphasizes on the study of different fuzzy structu...
