Phase quantization by pitch-cycle waveform coding in low bit rate sinusoidal coders

Soledad Torres, F. Javier Casajús-Quirós

A new phase coding algorithm is introduced in this paper, which works in the pitch-cycle waveform domain. It provides accurate phase coding at low bit cost. Its performance is analyzed inside a multiband excitation coder with improved onset representation. In this context, the introduction of original phase information by means of the proposed coding algorithm provides noticeable quality improvement without increasing the total bit rate of the coder.
