Abstract:
The present invention relates to a codec device and method for encoding/decoding voice and audio signals in a communication system, wherein: a fixed codebook excited signal is generated by using a pulse index for a voice signal; a first adaptive codebook excited signal is generated by using a pitch index for the voice signal; a fixed codebook signal is generated by multiplying the fixed codebook excited signal by a fixed codebook gain; a first adaptive codebook signal is generated by multiplying the first adaptive codebook excited signal by a first adaptive codebook gain; and a synthesized filter excited signal is generated by adding the fixed codebook signal and the first adaptive codebook signal.

Claim (Index 2):
A device of processing a signal, the device comprising:\n one or more processor is configured to: generate a first codebook excited signal; determine a first codebook using the first codebook excited signal and a first codebook gain; generate a second codebook excited signal; determine whether a filtering is applied to the second codebook excited signal using LPF (Low Pass Filter); determine a second codebook signal using a second codebook excited signal and a second codebook gain, wherein the second codebook excited signal is filtered by the LPF or is not filtered by the LPF; and combine the first codebook signal and the second codebook signal.
