Wavelet based decision feedback equaliser
Lin Lin, Yi Wang · Electronics Letters · 1997
A decision feedback equaliser (DFE) structure based on wavelets (WBDFE) is presented. The WBDFE shows faster convergence than the conventional DFE, with a very small increase in computation. In addition, the WBDFE has good time-frequency localisation, and is suitable for time-varing channels.
