VORRICHTUNG UND VERFAHREN ZUR KORREKTUR VON KANALFEHLERN |
摘要 |
To provide an approach to correction of residual errors in subband-based transmission schemes there is provieded a channel error correction apparatus with a first synthesis unit (12) for synthesizing a preliminary output signal from subband signals received via a transmission channel. A subband correcting is achieved through a subband reanalysis unit (14) analyzing the preliminary output signal through subband filtering without downsampling, an error estimation unit (16) estimating errors in subband reanalysis output signals using subband specific error patterns, and an error compensation unit (20) correcting the subband signals using error estimation results. A second synthesis unit (22) then synthesizes a final output signal from output signals of the error compensation unit (20). <IMAGE> |
