Abstract :

In this paper, a new approach of compressing sound signal based on the Walsh–Hadamard transform has been proposed. The compression issue is performed by considering limited interval in the transformed plane of the sound signal as a transmission data based on the knowledge that most of the energy of the signal is focused on high coefficients area of the Walsh–Hadamard transform. Consequently, on the receive side the sound signal is reconstructed using the inverse Walsh–Hadamard transform. The missing part of the transformed spectrum will be compensated with a calculated value for all coefficients in the missing part. The reconstructed sound signal is evaluated with the original sound signal using the standard metrics of signal accuracy. The simulation results from the proposed approach view significant percent of accuracy for the reconstructed signal.
