Pitch prediction for packet loss concealment

The pitch lag predictor (220) is provided for use by a speech decoder 200 to generate a predicted pitch lag parameter. Pitch lag predictor based on a plurality of previous pitch lag parameters configured to generate a first sum, and each of the plurality of previous pitch lag parameters and a plurality of previous pitch lag parameters with respect to the predicted pitch lag parameter, further configured to generate a second sum total to the basis of the position calculator 222; Further configured to generate a second coefficient using a first equation based on the first sum and the second sum configured to generate a first coefficient, and using the first sum and second equations based on the second sum, Here, the first equation and the second equation, and the other, the coefficient calculator 224; And it comprises a predictor (226) configured to generate a predicted pitch lag parameter based on the first coefficient and the second coefficient.Pitch lag parameter, the pitch lag predictor, a decoder, a voice, a coefficient calculator, picket loss concealment, total
