What is linear equalizer?

The Linear Equalizer block uses a tapped delay line filter to equalize a linearly modulated signal through a dispersive channel. Using an estimate of the channel modeled as a finite input response (FIR) filter, the block processes input frames and outputs the estimated signal.

What is linear equalization in wireless communication?

Linear equalizer: processes the incoming signal with a linear filter. MMSE equalizer: designs the filter to minimize E[|e|²], where e is the error signal, which is the filter output minus the transmitted signal. Zero-forcing equalizer: approximates the inverse of the channel with a linear filter.

What is LMS equalizer?

LMS algorithm is applied to equalize the effect of the channel. In this paper we take different value for step size in adaptive equalizer. The value for the step size must be used when the Least Mean Square (LMS) algorithm used to create an adaptive filter.

What is DFE in Matlab?

dfe = comm. DecisionFeedbackEqualizer creates a decision feedback equalizer System object to adaptively equalize a signal. example. dfe = comm. DecisionFeedbackEqualizer( Name , Value ) sets properties using one or more name-value pairs.
