A METHOD FOR CHANNEL EQUALIZATION USING A BASIS EXPANSION MODEL

摘要

A method of equalizing a signal received over a transmission channel defined by BEM coefficients of a basis expansion model of its channel taps, comprising the step of approximately solving the relation $\[ y\left[n\right]={\displaystyle \sum _{m=0}^M}{B}_m\left[n\right]\cdot \left({\displaystyle \sum _{l=0}^{L-1}}{b}_{\mathit{lm}}x\left[n-l\right]\right)+w\left[n\right] \]$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,B_m[n] being the mth basis function of the basis expansion model,M being the model order of the basis expansion model, andb_lm being the BEM coefficient of the mth basis function of the lth channel tap, andw[n] being optional noise.
