Blind Adaptive Channel Equalization with Performance Analysis
نویسندگان
چکیده
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 proposes a simple but effective iterative method to improve the performance. Simulation examples are demonstrated to show the effectiveness of the proposed method and the analyses.

On the Performance of a Turbo-Equalizer including Blind Equalizer over Time and Frequency-selective Channel. Comparison with an OFDM System
In this paper we study a receiver based on Turbo-Equalization where adaptive equalization and channel decoding are jointly treated in an iterative process. The novelty lies in the first stage equalizer that consists in a completely blind structure. This receiver scheme is there demonstrated to be well suited for transmissions over a time-variant and frequency-selective channel with a large dela...
متن کاملAdaptive Blind Equalization of QAM Transmitted Constellations across Linear Band-Limited Channel
ISI (Intersymbol Interference) severely degrades the performance of high speed digital communication systems. A popular technique for countering ISI is Adaptive Equalization. Blind/Unsupervized equalization is one class of adaptive equalization where initial training of equalizer’s weights is not feasible. Godard’s Constant Modulus Algorithm (CMA) was the very first blind equalization algorithm...

ISSN 2277 5080 | © 2013 Bonfring Abstract---Adaptive equalization is a well known method to minimize the Inter-Symbol Interference (ISI) in wireless communication. Often, adaptive algorithm requires transmission of known training sequence to track the time varying characteristics of the channel and hence utilizes additional bandwidth. It is also impractical to have training sequences in all typ...
متن کاملOn the Practical Aspects of Joint Passive Phase Conjugation and Equalization Underwater Communication Systems
Underwater acoustic communication systems suffer from the channel impairments which results in time spreading of the transmitted signal. In underwater environment, multiple replicas of the transmitted signal are received at the receiver through different paths, which causes significant Inter-Symbol Interference (ISI). Decision Feedback Equalizers (DFE) was utilized to overcome this type of inte...
