  Jordan Melzer (Communication Sciences Institute, USC)TITLE: Low complexity turbo-like codesTHESIS ADVISOR: Keith Chugg (USC)ABSTRACT: Error-control coding is a key feature of most modern
  communications systems, allowing close to a factor of ten in increased
  receiver sensitivity. We explore two aspects of low-cost error-control
  code decoders. First we design single decoders that provide competitive
  performance-complexity trade-offs over a wide range of operation. We
  introduce a new class of codes, show design rules and design techniques
  for this class, and design new codes in this class able to give, from a
  single decoder, extremely good performance over a range of decoding
  effort, block sizes, and code rates and give close to no performance
  penalty when generating rate-compatible codewords.
  The flexibility and
  competitive performance-complexity profile
  of these decoder designs
  allows them to be good choices both for systems that support a range of
  operating conditions and those
  that don't.Next we explore decoders with hardware errors. We show that
  error-control code decoders that have faults in memory may exhibit very
  little performance degradation and suggest design techniques that
  virtually eliminate the performance loss from a single
  error.
