- Abstract
A packet loss recovery technique based on interleaving is proposed for uncompressed high-fidelity audio transmission. The audio samples are interleaved for transmission to avoid burst errors. The lost samples in the receiver are estimated by using quadratic fit interpolation (QFI). Finally a low pass filter (LPF) is applied to the estimated data for suppressing high-frequency aliasing caused by data loss. Objective evaluation of the performance is given by the peak signal-to-noise ratio (PSNR). Simulation results show that the proposed method reconstructs the lost data effectively, and has good performance with respect to the PSNR.
