Abstract	Recently an approach that combined the techniques in distributed classification and the ones in error-correcting codes has been proposed to design a fault-tolerant classification system in wireless networks. The codeword implemented at the fusion center is assigned based on each phenomenon and each detection result of every sensor. A local decision represented by one bit is made according to the codeword and the detection result. Thus, the length of the codeword designed is equal to the number of sensors. In this paper, we propose a new distributed detection scheme combined with two-dimensional channel coding. Multiple detections are conducted by each sensor for the same phenomenon. A two-dimensional code that combines the designed code and a repetition code is implemented at the fusion center for decoding. The virtual code length of this two-dimensional code is the code length of the designed code multiplied with the number of detections conducted at each sensor. Compared with the previous methods, the new scheme has higher classification reliability and lower sensor complexity
