| Abstract(in English) | A binary symmetric channel (BSC) is considered in a binary tree network. End-nodes of the network are connected to a fusion center, which sums up decision data of the end-nodes to make a decision variable. When the decision variable is applied to a hard decision, the error probability of the fusion center was shown to be almost the same on the BSC crossover probability. In this paper, a probability density of the decision variable is demonstrated, and convolutional coding/soft decision Viterbi decoding is applied to the network. The error probability is analyzed to show the error probability improvement by coding. |
