Energy-conscious turbo decoder design: a joint signal processing and transmit energy reduction approach
Energy-conscious turbo decoder design: a joint signal processing and transmit energy reduction approach
Conventionally, the decoding energy consumption Epr of turbo codes were not a significant contribution to the overall energy consumption of a system, since the popular applications of turbo codes were focused on long-range communication systems, such as mobile phone networks or deep space communications. However, with advances in IC fabrication, sophisticated Error-Correcting Codes (ECCs), such as turbo codes, may be embedded into low-cost Wireless Sensor Networks (WSNs). In this paper, it is demonstrated that to design a turbo code for WSNs, the processing energy must be considered as an important factor during the early design stage. However, conventionally, the processing energy has not been considered in the design process, since no technique has been available for estimating it using conventional designs. Hence, we proposed a processing energy estimation framework for minimising the overall energy consumption of a turbo coded scheme at the code design stage.

Abstract
Conventionally, the decoding energy consumption Epr of turbo codes were not a significant contribution to the overall energy consumption of a system, since the popular applications of turbo codes were focused on long-range communication systems, such as mobile phone networks or deep space communications. However, with advances in IC fabrication, sophisticated Error-Correcting Codes (ECCs), such as turbo codes, may be embedded into low-cost Wireless Sensor Networks (WSNs). In this paper, it is demonstrated that to design a turbo code for WSNs, the processing energy must be considered as an important factor during the early design stage. However, conventionally, the processing energy has not been considered in the design process, since no technique has been available for estimating it using conventional designs. Hence, we proposed a processing energy estimation framework for minimising the overall energy consumption of a turbo coded scheme at the code design stage.
