Wavelet based adaptive equalization algorithm

Two equalizer structures based on orthogonal wavelet bases are proposed, named the wavelet based linear equalizer (WBLE) and wavelet based decision feedback equalizer (WBDFE). The equalizer is represented by a set of orthogonal wavelets and the corresponding coefficients. The paper also gives the adaptation algorithm. Simulation results show that the WBLE and WBDFE converge faster than the conventional LMS based linear equalizer and decision feedback equalizer, while the increase in the computational complexity is very low.
