A low-complexity waveform interpolation coder
@article{Kleijn1996ALW, title={A low-complexity waveform interpolation coder}, author={W. Kleijn and Y. Shoham and D. Sen and R. Hagen}, journal={1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings}, year={1996}, volume={1}, pages={212-215 vol. 1} }
A recent independent survey found a 2.4 kbit/s waveform-interpolation (WI) algorithm to perform better than other state-of-the-art speech coders. However, this coder had a very high level of computational complexity. The introduction of various techniques, including a time-varying waveform sampling rate and a cubic B-spline waveform representation, has reduced the computational complexity by an order of magnitude. The new implementation allows full-duplex real-time operation on a single DSP… CONTINUE READING
