A Field Experiment of Channel Equalizer for Echoes outside the Guard Interval at the Mizunami Relay Station

Abstract

We have researched and developed a channel equalizer to compensate the signal degradation caused by echoes outside the guard interval of an OFDM signal. This paper describes the result of field experiments of a prototype equalizer. In this experiment, trial equalizer was used at the Mizunami relay station in Gifu prefecture where is deterioration of an OFDM signal caused by the reflection waves from ships on the Ise Bay.
