Hi, We are working on GSM-FR codec. When we feed any one of the following test inputs to the decoder, the output is not matching with the reference output provided by the ETSI. The input sequences, which are resulting in the wrong outputs, are: Seq01_u.cod, Seq02_u.cod, Seq03_u.cod, Seq04_u.cod, Seq05_u.cod But the output of the GSM-decoder after m -law encoding, is matching with the output of the reference code supplied by the ITU-T (RPE-LTP as part of G191 standard which is equivalent to GSM FR) for the above inputs. Can anybody give reasons for this?. Can we presume that the decoder working properly? with regards K.Srinath |
