Abstract:
1. A method of synchronizing a first signal comprising data transmitted by a first transmitter and a second signal comprising the data transmitted by a second transmitter remote from the first transmitter , the first signal and second signal transmitted to a receiver in a coverage area of the first transmitter and the second transmitter, wherein the data comprises a plurality of data frames, each of the plurality of data frames having synchronization information having a constant value among the data frames, comprising the steps of: receiving the data in the first transmitter from a master transmitter; receiving the data in the second transmitter from the master transmitter; generating a first time offset between the synchronization information of the data received in the first transmitter and a global time reference common to the first transmitter and the second transmitter and independent from the data received by the first transmitter; generating a second time offset between the synchronization information received in the second transmitter and the global time reference common to the first transmitter and the second transmitter and independent from the data received by the second transmitter; generating first delayed data from the data received in the first transmitter delayed by the first time offset; generating second delayed data from the data received in the second transmitter delayed by the second time offset; transmitting the first signal having the first delayed data from the first transmitter, comprising modulating the first delayed data with a first carrier at a first frequency; and transmitting the second signal having the second delayed data by the second transmitter, comprising modulating the second delayed data with a second carrier at the first frequency; wherein the first carrier and the second carrier are synchronized to be in phase according to the global time reference.
