Frame error-robust MDCT bit reduction for G.729.1 by inter-frame correlation
Keunseok Cho, Sangbae Jeong, Minsoo Hahn · 2011
In this paper, a new algorithm for encoding spectral envelope in G.729.1 for VoIP is proposed. In order to reduce allocation bits, sub-band correlation between adjacent frames is utilized. By the proposed allocation algorithm, enhanced quality of sounds can be obtained even in frame error conditions.
