Wireless transceiver is a mandatory component of any kind of wireless sensors. Inside wireless transceiver, Viterbi decoder (VD) is needed to improve the decoding performance of the transceiver. In this paper, we propose a low complexity Viterbi decoder algorithm for wireless sensors that aim to support Internet of Thing (IoT) applications. Our algorithm is named as K-min Viterbi decoder because only...
This research is our first step on the purpose of developing low-complex Viterbi decoder for IoT applications. We evaluate how the values of Viterbi decoder's parameters such as trace back length (L), input data bit-width (D), and LLR truncated value (E), affects to BER and PER of a communication system. The IEEE 802.11ah simulator is used with AWGN channel and BPSK modulation. Our simulation results...
