NOISE ANALYSIS OF SINGLE CHANNEL DEGHOSTING FILTERS

Abstract

Arrays of performance values showing the change in additive noise variance due to single channel deghosting indicate significant sensitivity to both the deghosting method and band pass filtering. Only part of the echo can be removed feasibly, for example, with less than one db increase in the noise, by the single channel deghosting filter. The maximum fraction of the echo which can be removed varies greatly with the echo time, especially if the noise was band pass filtered.
