Abstract :
A simplification of the MAP decoder for use in turbo decoders is presented. The simplification eliminates the need for a ROM or multiplexor-tree lookup table and replaces it with a constant value. Simulations show that the performance of turbo decoders is not adversely affected by this simplification
