Analog Codes on Graphs

  title={Analog Codes on Graphs},
  author={Nandakishore Santhi and Alexander Vardy},
We consider the problem of transmission of a sequence of real dat produced by a Nyquist sampled bandlimited analog source over a band-limited analog channel, w hich introduces an additive white Gaussian noise. An analog coding scheme is described, which can achieve a mea n-squared error distortion proportional to (1 + SNR)−B for a bandwidth expansion factor… CONTINUE READING
