Wireless Sensor Network (WSN) consists of limited energy resources, which reduce the processing capabilities and a radio frequency communication unit with limited transmission power. In wireless communication, Automatic Repeat reQuest (ARQ) technique are used which has power loss in packet retransmission. Then Error Correcting Code (ECC) can be used to reduce the number of packet retransmission Turbo codes are error correcting codes with at least two dimensions (i.e. each datum is encoded at least twice). The decoding of turbo codes is based on an iterative procedure using the concept of extrinsic information. Highly parallel decoders for convolution turbo codes have been studied by proposing two parallel decoding architectures and a design approach of parallel interleaves.
