Abstract

Bir birinci arastirici, bir birinci kanali (örnegin bir yayin kanalini) arastirmaktadir bir ikinci arastirici bir ikinci kanali (örnegin, bir trafik kanalini) arastirmaktadir ve ikinci arastirici ikinci kanali arastirmak üzere birinci arastirici kaynakli bilgiyi kullanmaktadir. Bulusun bir veçhesine göre, birinci arastirici, birinci kanal için bir gecikme profili türetmektedir. Ikinci arastirici, ikinci kanal için bir baglantilar kümesi türetmek üzere gecikmeyi kullanmaktadir.
