IPC: H04L27/34
Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To provide an in-band diversity transmission method that realizes effective fading countermeasures while making the most of features of a conventional in-band diversity method by especially solving a problem of the conventional in-band diversity method that doesn't have sufficient effects against fading caused over the entire transmission band among diversity methods widely used to prevent increase in a data error due to fading.

IPC: F01N1/00
Filed: 2000-03-30
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation in the identification accuracy of a secondary sound path C by identifying the secondary sound path C under a condition under which the signal-to-noise ratio of an identification sound is degraded. SOLUTION: A signal level of a false signal m(k) is regulaed in such a manner that the level of the identification sound released from a speaker 5 when the secondary sound path C is identified is approximately equaled to a level of the exhaust sound after silencing obtained by collecting the sounds by an error microhone 7, i.e., a level Ve of an error component. Under the condition, under which the silencing effect of some extent is obtained, the level of the identification sound is relatively smaller than the background of the silencer itself as a reference and the signal-to-noise ratio of the identification sounds is degraded. Then, if the secondary sound path C is identified under such condition, the identification accuracy of the secondary sound path C is degraded.  The operation of an LMS arithmetic section 10 is thereupon controlled by a control section 14 in such a manner that the execution of the identification operation of the secondary sound path C is made infeasible when the level Ve of the error component is low, i.e., when the level of the identification sound is low.
