15-5 A Field Experiment of Digital Terrestrial Broadcasting Reception in Co-Channel Interference Environment : Experimental Comparisons of Pre-FFT Array and Post-FFT Array

Abstract

Along with the installation of a large number of relay stations for digital terrestrial broadcasting, co-channel interference occur in part of service area. As a countermeasure against co-channel interference, we have developed an interference canceller using adaptive array technology and have experimental omparisons of a Pre-FFT type canceller and a Post-FFT type one in a real field.
