D-2-1 スペクトル拡散を応用した人体近傍電界通信技術による生体情報の伝送 : 歩行時における誤り率の改善(生体計測(1))

As a novel vital sign monitor, we have developed wireless ECG monitoring system with Near-field intra-body communication (NF-IBC) technique enhanced by spread spectrum (SS). However, communication reliability was not so high in ambulatory status. In this paper, we added error correcting code improve BER performance with (8,4) extended Hamming code. The test result shows that (8,4) extended Hamming code can correct error completely under low BER. However, the results also shows that (8,4) Hamming code can not correct error when multiple errors occurred in a packet.
