ADAPTIVE TRANSVERSAL FILTERS FOR MULTIPATH COMPENSATION IN MICROWAVE DIGITAL RADIO

摘要

This paper describes the implementation of adaptive transversal filters and their appli cation in wideband microwave line of sight digital radio systems. These filters are attractive for use in multipart reduction as they can compensate for both minimum and non-minimum phase multipath fades. The relative performance of symbol (T) spaced and T/2 spaced linear transversal equalisers are assessed by computer simulations which compare the error reduction obtained with different numbers of equaliser taps and various levels of input signal quantisation and arithmetic accuracy in these decision directed equalisers.
