15th International Conference on Pattern Recognition (ICPR'00) - Volume 3 Channel Optimized Matrix Quantizer (COMQ) in CELP Coding Barcelona, Spain September 03-September 08 ISBN: 0-7695-0750-6
In this paper, we present a study of channel optimized matrix quantizer (COMQ) applied to quantize LSP parameters in a CELP (Code Excited Linear Prediction) coder. A modification of the DoD FS-1016 standard {Campbell89} is used for this purpose. A Gaussian channel is considered as the channel through which information is sent and BPSK (Binary Phase Shift-Keying) is used as modulation technique. To measure the performance of this coder several channel signal to noise ratio (CSNR) are considered. In addition, the performance of FS-1016 standard coder is computed for comparison purposes.
