An Error Control Method with Linear Block Code in Sensor Networks

Abstract

An error control method is investigated and obtained by combination of the modulation and linear block code in sensor networks. The constructed coding scheme is multistage decoded using a new low-complexity soft-decision decoding method in sensor networks. Computer simulations of the proposed method are presented and compared with the reunion junction technique. The proposed method shows a better performance than the reunion junction technique. The low complexity of the method allows the use of long linear block codes. It is possible to construct an efficient bandwidth multilevel code on signal set partitioning. A wide range of design tradeoffs are possible with multilevel codes. Composite codes are possible using component codes.
