An efficient way to reduce the dynamic power dissipation in the turbo decoder is presented. This technique is based on dynamic re-encoding of the received messages. The idea is to decrease the state transition activity of the trellis-based algorithms by replacing the classical direct decoding of the random noisy codewords by an equivalent decoding of almost ‘all zero’ codewords in order to keep the survivor path on the ‘zero path’.
