Rate-distortion function for α-stable sources
AEU - International Journal of Electronics and Communications(2016)
摘要
In this paper, we develop a numerical approximation based on the Blahut–Arimoto algorithm to the rate distortion function of sources with α-stable distribution both for the symmetric and the skewed cases. The calculated rate-distortion function provides bounds for lossy source coding/data compression and the achievable rates for a given distortion.
