Abstract :
We present a new soft decision decoding method for partial unit memory (PUM) codes. The method exploits the linearity of the parallel transitions in the trellis associated with such a code. We provide bounds on the number of operations per decoded bit, and show that this number is dependent on the weight hierarchy of the linear block codes associated with the parallel transitions
