  • Title: An LDPC decoder architecture for wireless sensor network applications.
    Author: Biroli AD, Martina M, Masera G.
    Journal: Sensors (Basel); 2012; 12(2):1529-43. PubMed ID: 22438724.
    Abstract:
    The pervasive use of wireless sensors in a growing spectrum of human activities reinforces the need for devices with low energy dissipation. In this work, coded communication between a couple of wireless sensor devices is considered as a method to reduce the dissipated energy per transmitted bit with respect to uncoded communication. Different Low Density Parity Check (LDPC) codes are considered to this purpose and post layout results are shown for a low-area low-energy decoder, which offers percentage energy savings with respect to the uncoded solution in the range of 40%-80%, depending on considered environment, distance and bit error rate.
