Abstract

   This article presents the prototyping of a Golay (23.12.7) Error Correcting Code encoder and decoder using a FPGA. Golay (23.12.7) CODECs implementations were done using LabVIEW as CAD environment, having as hardware support NI ELVIS II+ DE FPGA Board. Efforts were focused on highlighting CODECs usability within WSN by making an assessment from hardware and power consumption constraints vs. data integrity points of view. Practical test results were over-satisfactory (i.e. the circuits work very well, the balance between typical WSNs constraints and usability/necessity of the CODEC was achieved) thus proving CODEC’s suitability for usage within WSNs, as a mechanism to ensure data integrity. platform equipped with
