Abstract :
In the past few years, several approaches to low complexity turbo-like code designs have appeared. All of these code designs are based on very simple graph structures or 2-state trellises that result in low decoder complexity. One such approach is based on multiple turbo codes. The low complexity multiple turbo code designs are compared to 8-state turbo codes used in third generation mobile systems on the basis of error performance and computational complexity.
