Popis: A new phase coding algorithm working in the pitch-cycle waveform domain is introduced. It provides accurate phase coding at low bit cost, thus being suitable for low bit rate sinusoidal coders. Its performance is analysed inside a multiband excitation (MBE) 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 significantly increasing the complexity and total bit rate of the coder.
