<p>Methods for synchronizing a plurality of RF transmitters (20) that are supplied with a common digital information signal for carrier modulation and subsequent transmission a common channel throughout a prescribed region, whereby digital signal receivers within the region receive transmissions on the channel from more than one transmitter (20). The method involves inserti ng reference signals into the data sent to transmitters in order to place them into known states at specific times relative to the digital signals sent to them for transmission. The digital signals transmitted by each transmitters will be identical to one another so that the receivers are identical to one another so that the receivers can identify one received signal as a main signal and the others as echoes. The signal transmitted by at least one of synchronized transmitters is delayed, such that identical digital signals received from at least two of the transmitters by receivers in the region arrive at each receiver within a prescribed time window.</p> |
