Abstract: In this paper, our focus is on energy efficient coding schemes for wireless sensor networks. A source coding and modulation technique for reducing multiple access interference (MAI) as well as for reducing power consumption in MC-CDMA wireless sensor network systems is presented. In all our analysis we consider perfect power control mechanism. Source symbols are represented by a special coding, termed Minimum Energy coding (ME coding), which exploits redundant bits for saving power when transmitted via RF links with On-Off-Keying. This ME coding is applied to MC-CDMA sensor network systems in order to reduce MAI as well as to reduce power consumption. The proposed method is aptly suitable for wireless sensor video node in application of video coding.

TL;DR: In this article, the authors propose an enhancement to the above technique by leveraging the notion of short-lived operands (values targeting the registers that are renamed by the time the instruction producing the value reaches the writeback stage).
Energy scalable system design
TL;DR: The notion of energy-scalable system-design is introduced and transforms that significantly improve scalability are analyzed using three distinct categories of commonly used signal-processing algorithms on the StrongARM SA-1100 processor as examples.

TL;DR: A more conservative result is obtained due to a better characterization of the average energy per source bit and it is shown that hard-decision decoding outperforms BPSK only when the SNR is higher than a certain threshold and that soft-dec decision decoding performs better than B PSK regardless of theSNR value.
