Evaluation of algorithm optimizations for low-power Turbo-Decoder implementations

Energy aware and low-power implementation of Turbo-Decoders are a must for 3GPP and other communication system designs. This paper explores a reduced-search maximum-a-posteriori algorithm usually referred to as a low-power strategy for implementation. Synthesis results indeed show a noticeable power saving potential in the absence of iteration control. In the presence of iteration control, however, this paper shows that it even leads to an increased power consumption.
