In this paper, we present an enhanced EDSVQ method namely EEDSVQ to quantize the differential LSFs. The EEDSVQ method can prevent the quantization error propagation efficiently. According to the intra-frame correlation coefficients of differential LSFs, we propose an optimal partition scheme for EEDSVQ method. The simulation results show the EEDSVQ method(More)
