Abstract

Turbo codes typically utilize time-invariant component codes whose total encoder memory is no greater than 4. In this letter, turbo codes with time-varying component codes are studied via EXIT analysis, distance spectrum analysis and simulation. Turbo codes with time-varying component codes and memory 6 are shown to have similar performance in the waterfall region and superior performance in the error floor region when compared to both the original memory 4 Berrou turbo code and the memory 8 Big Numerator-Little Denominator turbo codes.
