Method for channel equalization

摘要

A method of equalizing a signal received over transmission channel defined by BEM coefficients of a basis expansion model of its channel taps, comprising the step of approximately solving the relation (I) for x[n] by an iterative method, n being the index of time, y[n] being the received signal, x[n] being the equalized signal, Bm[n] being the mth basis function of the basis expansion model, M being the model order of the basis expansion model, and blm being the BEM coefficient of the mth of the basis function of the lth channel tap, and w[n] being optional noise.;y⁡[n]=∑m=0M⁢Bm⁡[n]·(∑l=0L-1⁢blm⁢x⁡[n-l])+w⁡[n](I)
