ABSTRACT:
Speech signal encoding at a low bit rate is realized by decreasing the number of arithmetic operations required to determine LPC parameters in a backward processing unit. These parameters are determined and updated by filtering, rather than by impulse response. In this manner, it is not necessary to use previously-calculated parameters in updating.
