摘要Abstract: In this paper we propose a CELP ECG codec for medical telemetry. The encoding algorithm is based on CODE-EXCITED LINEAR PREDICTION(CELP). The general framework proposed is: QRS detection, calculation of LPC parameter, generation of residual error signal, codebook generation, MSE(Mean Square Error) search.The codebook is generated for residual error.The Indices of the codebook and corresponding LPC parameters are transmitted where the minimum MSE occurs. A replica of the transmitter codebook is present at the receiver.Corresponding to the received index value residual error coefficients are retrieved from the receiver codebook.The ECG signal is reconstructed from the retrieved code word.
