Abstract :
We consider message-passing strategies for the iterative decoding of multiple turbo codes (MTCs). We contradict the conventional wisdom that the parallel decoding structure is the best for MTCs by proposing new non-parallel decoding structures which give better BER performances for the same computational complexity. Under a modified independent Gaussian assumption (IGA), we are able to theoretically validate our design, which is further supported by extensive simulation results
