The adaptive filterestimates the echo path, based on which a replica of the echo is created and subtractedfrom the combination of the actual echo and the near-end speech signal. The basic components of anecho canceller are an adaptive filter, and a double-talk detector. The objective of this thesis is to find out a good echo removal algorithm, which iscapable of providing convincing results for PC application. However, traditional methodsare not sufficient. The solution to these problems is the elimination of the echowith an echo cancellation or echo suppression algorithm. However, the presence of a large acousticcoupling between the loudspeaker and microphone would produce a loud echo that wouldmake conversation difficult. Today people aremore interested in hands-free communication with the use of a loudspeaker and amicrophone, in stead of a normal telephone. The communication technique has changed a lot in the recent years. 2007 (English) Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE credits Student thesis Abstract
