Abstract :
High-speed TDMA wireless networks require high data rate efficiency and fast turnaround times. In dispersive multipath channels, an equaliser is needed to remove ISI from the signal. The equaliser may be trained more quickly if its taps are preloaded with initial values. The paper describes a fast start-up equaliser which uses a power ratio approximation to estimate the initial tap values. The authors report on the performance of the fast start-up equaliser on data measured in an indoor radio environment
