2D Wavelet Transform Based Compression of Pseudo-periodic Signals

This paper attempts to utilize the pitch synchronous property of Pseudo-periodic signals to increase the efficiency of compression, to minimize losses and thus to enhance the quality of the reconstruction. Results show higher signal to noise ratio, higher compression ratio and lower percentage distortion with the new method of 2-D compression as compared to 1-D compression. A new method is used for pitch peak detection of voiced signals using k-means clustering algorithm.
