JRC has developed burst mode equalizer for digital wireless communication systems of business applications. The purpose of this equalizer is to secure communication quality under frequency selective fading channels caused in mountain areas or high-rise buildings areas. Adaptive equalizer combats intersymbol interference (ISI) on the received signal which degrades the performance significantly. JRC has studied the adaptive equalizer adopted for burst frame signals, called burst mode equalizer. The burst mode equalizer has been applied to conventional digital burst modem. This paper describes problems and solutions to develop the burst mode equalizer.
