  • Abstract
    Since the introduction of turbo codes a large amount of research effort has been spent on improving turbo coding performance. One way of improving the performance is to choose the best constituent codes. Previously the constituent codes have been chosen by maximising the input weight 2 effective free distance deff2. The number of nearest neighbours Neff is also an important parameter. This paper presents a list of constituent codes that maximise deff2 and minimise the Neff. By choosing constituent codes that minimise Neff the performance of turbo codes can be improved with no increase in complexity
