| Abstract(in English) | To realize the wireless integration of many medical equipments, a fundamental study was conducted. The possibility of multichannel data-transmission using a spread spectrum technique and indirectlight communication was investigated. Instead of ASK, PSK was used for the primary modulation. For the error control, ARQ technique was introduced. The input level of a SAW convolver was stabilized with an AGC circuit. With these improvements, the data transmission became possible even in the condition with a negative CNR. In ECG transmission, the quality was satisfactory even when the CNR is close to zero. The problem was found that the quality was degraded as soon as the CNR became less than -1. |
