Embodiment Construction
[0021] The present invention will be further elaborated below in conjunction with the accompanying drawings.
[0022] As shown in Figure 1, the multiple diversity transmitting and receiving device of the mobile digital multimedia broadcasting system consists of two satellites, a ground station 2 and a receiving terminal 3. There is one S-band on each satellite, the frequency of the two S-bands is different, there is an interval of 1MHZ, and the bandwidth is at least 8MHZ. There is a 1-second delay between the signals transmitted on the S-band of the two satellites. Ground station 1 is in the UHF band, with a bandwidth of at least 8MHZ, and ground station 1 is 1 second longer than the longest delay of the two satellites. The receiving terminal 3 uses a broadband antenna and three independent signal receiving devices that can simultaneously receive the S-band transponder and the UHF-band ground station 2 to receive the data of the S-band and the ground station 2 of the two sate...
