Research on the Identification Method of Transmitter Recognition in CMMB Wireless Networks

ABSTRACT

This papers designs the identification method of transmitter recognition in wireless networks by analyzing the wireless networks and the physical frame structure of China Mobile Multimedia Broadcasting(CMMB) system. The method calculates the time from the signal of preset transmitter to the measurement site according to the preset transmitter location information, the measured identification signal information of transmitter and the location information of measurement location. And then compare the time that the preset transmitter signal reaches the measurement site and that of the measured transmitter signal reaches the measurement site. Finally, it judges the preset transmitter identification corresponding to the concrete measured transmitter identification. The method can accurately recognize every transmitter when there are many transmitters with same autocorrelation value in the preset transmitter recognition, which is benefit for the optimizing of CMMB wireless networks.
