Hybrid digital-analog source-channel coding with one-to-three bandwidth expansion
We consider the problem of bandwidth expansion for lossy joint source-channel coding over a memoryless Gaussian channel. A low delay 1∶3 bandwidth expansion hybrid digital-analog coding system, which combines a scalar quantizer and a 1∶2 nonlinear analog coder, is proposed. It is shown that our proposed system outperforms the 1∶3 generalized hybrid scalar quantizer linear coder in terms of signal-to-distortion ratio (SDR). A lower bound on the system SDR is also derived.
