Title
Improved Frame Loss Recovery Using Closed-Loop Estimation Of Very Low Bit Rate Side Information
Abstract
In CELP coders, the past excitation signal used to build the adaptive codebook is known to be the main source of error propagation when a frame is lost. This paper presents a novel resynchronization technique using very low bit rate side information to correct the past excitation signal after a frame erasure, the novelty being that the correction is computed in a closed loop fashion, based on the actual error introduced by the concealment. Subjective test results show that this approach is a promising area for future research on frame loss recovery.
