Performance analysis of a RLS-based MLP-DFE in time-invariant and time-varying channels
نویسندگان
چکیده
In this work, a recently derived recursive least-square (RLS) algorithm to train multi layer perceptron (MLP) is used in an MLP-based decision feedback equalizer (DFE) instead of the back propagation (BP) algorithm. Its performance is investigated and compared to those of MLP-DFE based on the BP algorithm and the simple DFE based on the least-mean square (LMS) algorithm. The results show improved performance obtained by the new structure in both time-invariant and time-varying channels. As will be detailed in this work, the newly proposed structure is a compromise between complexity and performance. © 2007 Elsevier Inc. All rights reserved.

Multilayer perceptron-based DFE with lattice structure
The severely distorting channels limit the use of linear equalizers and the use of the nonlinear equalizers then becomes justifiable. Neural-network-based equalizers, especially the multilayer perceptron (MLP)-based equalizers, are computationally efficient alternative to currently used nonlinear filter realizations, e.g., the Volterra type. The drawback of the MLP-based equalizers is, however,...

متن کاملRLS Algorithm with Variable Forgetting Factor for Decision Feedback Equalizer over Time-Variant Fading Channels
In a high-rate indoor wireless personal communication system, the delay spread due to multipath propagation results in intersymbol interference (ISI) which can signi cantly increase the transmission bit error rate (BER). Decision feedback equalizer (DFE) is an e cient approach to combating the ISI. Recursive least squares (RLS) algorithm with a constant forgetting factor is often used to update...

متن کاملCommunication Theory Joint channel estimation and equalisation of fast time-varying frequency-selective channels
This paper addresses joint channel and data estimation for transmission over frequency-selective and timevarying channels based on a Doppler-variant channel impulse response (CIR). A discrete spreading function (DSF), which corresponds to the Doppler Fourier series of the time-varying channel taps, is introduced. The spectral leakage associated with the Fourier series representation is reduced ...
