Hybrid Digital–Analog Source–Channel Coding for Bandwidth Compression/Expansion

  title={Hybrid Digital–Analog Source–Channel Coding for Bandwidth Compression/Expansion},
  author={Mikael Skoglund and Nam C. Phamdo and Fady Alajaji},
  journal={IEEE Transactions on Information Theory},
An approach to hybrid digital-analog (HDA) source-channel coding for the communication of analog sources over memoryless Gaussian channels is introduced. The HDA system, which exploits the advantages of both digital and analog systems, generalizes a scheme previously presented by the authors, and can operate for any bandwidth ratio (bandwidth compression and expansion). It is based on vector quantization and features turbo coding in its digital component and linear/nonlinear processing in its… CONTINUE READING
