Disclosed herein is a demodulation method in wireless telemetry systems using frame combining. In detail, this invention is related to the CDMA wireless communication systems, especially a demodulation method by frame combining method which uses time diversity in a wireless measuring instrument that is used for wireless telemetry systems. In transmission data of the present invention, CU(Control Unit) transmits the same frame repeatedly several times and RT(Remote Terminal) combines the transmitted frame, which improve signal-to-noise ratio of signal that is demodulated. Therefore, according to the present invention, there is effect that can minimize RT's hardware complexity and reduce electric power consumption, and reduce production costs of modem. |
