Optimal Audio Transmission over Wireless Tandem Channels

Optimal Audio Transmission over Wireless Tandem Channels
In this paper, we propose a statistical optimization framework for transmitting audio sequences over wireless links. Our proposed framework protects audio frames against both temporally correlated random bit errors introduced by a fading channel and packet erasures caused by network buffering. Forming a two-dimensional grid of symbols, our framework forms horizontal packets that are compensated only vertically against both types of errors. The utilized one-dimensional error correction coding scheme of our framework assigns parity bits according to the perceptual importance of frames such that the Segmented SNR of a received audio sequence is maximized. In addition, the proposed framework suggests an effective way of reducing the packetization overhead of small audio frames.
