Abstract

  • In today's communications world channel coding underlies the physical layer of all major communication systems. For example: algebraic block coding (Reed-Solomon codes) are used in the CD and DVD standards, convolutional codes are widely used in wireless systems such as GSM,IS-95 and LANs (IEEE 802.11), trellis coded modulation is used in line modems and low-density parity check codes (LDPC) will be used to combat packet losses in future internet content distribution networks.
  • This course provides an introductory but thorough background in modern coding theory and covers both classical coding theory (block and convolutional codes), coding for bandlimited channels (Coded Modulation) and the modern theory of randomlike codes with iterative decoding (LDPCs, Turbo Codes).
